LifeSpan TR1200-DT3


Review Summary

Yesteryear’s most popular office treadmill, the advent of the TR1200-DT3 back in 2011 helped to kick off the treadmill desk revolution. The original design had a great reputation for being a solid middle-of-the-road offering. Not too expensive and relatively reliable for a typical single-user, home office usage profile. The company had a decent service network and to the degree that it was as good as anyone else’s, an industry leading warranty. Things started to change around 2018, however, when the founders and eventually the entire Utah-based management team would see the last of their days with the company after nearly 20 years. Lifespan would succumb to its debts and be taken over by Strength Master of Taiwan, its exclusive manufacturing partner. In the ensuing years, and particularly through the pandemic, the company went through a series of component quality reductions and price increases in the name of profit margins, going so far as to eliminate all treadmill factory warranties (you now have to pay more for an “extended” warranty, within 30 days of purchase, and good luck doing that if you didn’t buy it at time of purchase from Lifespan directly) in order to have any warranty at all. And even if you did, good luck getting through to service. There is no longer even a phone number on the website. So with all these headwinds against the company, and the massive brain drain of personnel that built the once-proud brand in the USA, we sadly have to revoke our long-standing recommendation of Lifespan’s treadmill desk products, including the TR1200-DT3 (aka TR1200 Glowup).

“Extended” warranty coverage must be purchased as an add-on, Lifespan no longer includes the standard factory warranty in the price of the product. $159.99-$309.99 for the TR-1200 (not available through Amazon).


The TR1200 is only sold with Lifespan’s “Retro” desktop controller for this price. Membrane keypad type with just the basics: speed, time, distance, step count and calorie burn. Users can upgrade to the new OmniHub controller for +$100, with Bluetooth (we have not lab tested this option yet). OmniHub supposedly includes Bluetooth although it’s unclear what software it may work with.

Customer Experience
Quality and Aesthetics
Positives The original TR1200-DT3 is unquestionably the most popular treadmill desk ever made, with many thousands of units in the field. It was well-built and had good warranty coverage. While not the original treadmill desk (that was the outlandishly overpriced Steelcase Walkstation) it was the first treadmill desk "for the rest of us."
Negatives Recent changes at the company have forced us to remove our "buy" recommendation from this product. It has been severely cost reduced to the point of significantly lowering its reliability, while the factory warranty was completely eliminated and the price was significantly increased. Less steel in the frame means more flex in the frame and more problems with belt tracking. The rampant complaints about lack of a phone number and general difficulty in reaching customer service for repairs are downright frightening. As company ownership shifted to Asia and the US management team walked out the door, systemic problems have arisen at Lifespan that seem to have gotten much worse through the pandemic. Electronics issues with the "Retro" controller are causing many users frustration.

Bottom Line

The field of bona fide options in the treadmill desk world has been significantly reduced over the past ten years, as many more companies have failed to find their niche than survived the battle. For most of that time Lifespan was the undisputed market leader, and the TR1200-DT3 was the king of the kill in terms of market share, being both affordable ($999) and rugged enough for the average user in single-user home office environment. With recent cost reductions to the componentry and build quality, combined with the complete DELETION of its factory warranty coverage, plus a significant price increase, the step function between the TR1200 and a bullet-proof treadmill desk, like the industry's top-rated iMovR Thermotread GT, isn't that great anymore. One has to seriously question whether taking a risk on the downgraded TR1200 design is worth it to begin with. But in light of recent changes that have seen twenty years of US-based management talent leaving the company and turning operations over to their new Taiwanese owners, the phone number being removed from the website and countless complaints from customers that it has become incredibly hard to reach anyone for service, we are forced to revoke our positive recommendation on Lifespan products that had held for nearly a decade.

The Lifespan Fitness Backstory

The founding editors of this website got the gumption to launch WorkWhileWalking (and WorkWhileStanding, which eventually merged into this site) back in 2012, specifically because Lifespan Fitness made a bold entry into the treadmill desk marketplace that finally legitimized it. Prior to their arrival, there were only three options for someone who wanted to have a treadmill desk: a) Steelcase’s insanely overpriced and unreliable Walkstation Treadmill Desk, b) the now-defunct, incredibly poorly-made TreadDesk or Signature Treadmill Desk alternatives to the $5000 Steelcase unit, or c) taking the DIY route by hacking a rehab treadmill into a reasonably reliable, slow-speed treadmill desk.

Lifespan was the first legit player to commercialize the treadmill desk with a reasonably-priced range of products to suit almost every customer type. These included the flagship TR1200-DT3 office treadmill, the lower-cost TR800-DT3 and the heavy-duty TR5000-DT3, as well as the DT5 and DT7 integrated treadmill desk workstations with their manually and electrically height-adjustable standing desks, respectively. Tens of thousands were sold to corporations, government, education and residential home offices over the past decade. Lifespan treadmill desks would regularly appear in TV shows from The Good Wife to Alpha House.

Lifespan’s foray into active office workstations eventually attracted many competitors into the field (see our round-up review of all the under-desk treadmill bases and all the top-rated treadmill desk systems); most of which, at this stage of the game, have already joined the Dead Pool. Quite a few big brand names in cardio equipment and a few misguided startups chased this shiny object only to find out that building and marketing a good treadmill desk would take a lot more than just removing the large pedestal console and replacing it with a desktop controller to make room for an actual desk. The only serious competitor Lifespan has ever had since 2015 has been iMovR, which stands stronger than ever with its premium-grade, enterprise-class ThermoTread GT treadmill base, and a wide array of integrated treadmill desk systems build around it such as the Lander Treadmill Desk.

Lifespan’s DNA was definitely formed in the crucible of sports equipment development, though, and this really showed in their rather pitiful offerings on the desk side of the treadmill desk combo. When asked, ergonomists shunned all treadmill desks for a long time because the Lifespan DT5 and DT7 rendition were all they’d ever seen at a trade show. Eventually, Lifespan caved and started to offer an ever-changing variety of standing desk alternatives, sourcing commodity-grade options from their factory peers in China and just bundling them with their treadmill bases. The DT5 and DT7 were eventually removed entirely from the Lifespan website, though they are still being blown out through Amazon.

At present, the only desks sold in bundles with the treadmill bases on Lifespan’s website are the generically-named Lifespan Fitness Standing Desk, which we’ve reviewed separately. Like the DT5 and DT7 desks, the new “Power Desk” line that’s based on this desk commits the same original ergonomic sin. Between the user and their keyboard is situated a deep forearm resting cushion with an embedded console for controlling the treadmill. This forces the user into a shoulder-forward posture as they type with their upper body weight resting on their forearms to maintain stability. At least that’s how the company liked to demonstrate it at trade shows and in videos. Lifespan Fitness’ desk offerings have always been incompatible with the installation of ergonomic keyboard trays, especially the old-school DT5 and DT7 models.

LifeSpan TR1200-DT3

While the company has never had any certificated ergonomists on staff, and always knew vastly more about working out on cardio equipment than they ever did about office workstation ergonomics, the current marketing team understands even less. Shockingly less. Perusing some of their recent social media postings we found numerous publicity shots, like this one here, that will curve your spine just looking at them. Here we have a TR800 “Classic” treadmill desk set to a fixed sitting height, with a birch standing desk converter on top of it. For all the hardware in this photo, there is no ergonomic monitor to hold up the display so the user’s neck is craning down, while the model is fake-typing in a completely unergonomic posture. What exactly is the point of putting a converter on top of an adjustable-height desk? More importantly, what is the point of using a treadmill desk in such a way as to create multiple potential ergonomic injuries? What is the point of setting a treadmill desk at sitting height, not walking height? So many questions.

Another tipoff that Lifespan’s marketing team doesn’t know the first thing about office fitness is that they’ve rebranded all their standalone treadmill bases from “-DT3”, e.g. the TR800-DT3 which they still sell on Amazon, to “Glowup” as in the TR800-Glowup that they market on their own website. (There don’t appear to be any differences between these other than the fact that the prices on the Amazon listings can be as much as several hundred dollars cheaper on some days.) But the term “glowup” really gets us, because as we’ve long said, “if you’re sweating while treadmill desking, you’re doing it wrong.”

Lifespan marketing materials often refer to walking at your desk as “a workout” instead of what it’s supposed to be: introducing healthy movement into your sedentary work routine. Sweating at your desk is anathema to the goal of treadmill desking, where you want that extra oxygen going to your brain, not your muscles. If you need some cardio exercise you should get it at the gym, not the office. As many years of Mayo Clinic research has supported, the goal is always to keep your heart rate and metabolic rate in the NEAT Zone. Perhaps this is one reason Lifespan Fitness never sought NEAT Certification; they’ve always left the top-end speed of their under-desk treadmills at 4.0 mph, way higher than the recommended 1-2.5 mph speed most office workers use, in order not to turn away customers who literally wanted to jog at their desks—with all the implied injury risks that entails.

Change of Command

Originally founded by ex-IBM sales account manager Pete Schenk after the dot-com bubble burst in the summer of 2000, the company ran with his hand on the tiller for 19 years. Not the actual manufacturer of any of these products, Salt Lake City, Utah-based Lifespan Fitness (technically, Park City Entertainment) had negotiated the exclusive distribution rights in North America and Europe for gym equipment products, and later treadmill desk and cycle desk products—all manufactured by Strength Master, a mid-tier manufacturer of cardio fitness equipment based in Taiwan and China.

It’s unclear how much ownership control the Taiwanese management team had over Lifespan prior to Schenk’s departure, but contrary to impressions the US-based company liked to put out to the world, the Utah contingent never really had much design input into the products they sold. This led to challenges over time. The company was never really in charge of its own destiny, and only had the management bench strength to be a capable distributor, not an actual technology innovation leader in the industry. The company that is always pushing the technology and ergonomic research on treadmill desks has always been and remains iMovR. (iMovR also partnered with The Mayo Clinic to publish the only solid research on things like How Many Calories Can You Really Expect to Burn Using a Standing Desk or Treadmill Desk?)

Lifespan Fitness itself did not employ any engineers. This led to long-standing problems with some features, especially those around Bluetooth and the smartphone app, which never worked reliably and still don’t. Product reliability was always a concern because the Taiwanese factory wanted to make one treadmill base for both cardio fitness and office workstation applications. In fact, the service manuals for the office treadmills and running treadmills (e.g. TR800i, TR1200i) are exactly the same. This instigated a fundamental conflict as to where to set the gearing ratios on the motor-flywheel-pulley-head roller power transmission system. The consequence of this is that the office treadmills have never had sufficient torque at low speeds, like the 1-2 mph speed that most workstation users are walking at. This led to a shortened useful life span for the costly motor, and mounting warranty claims over the years. (We get into all the nerdy details on this issue in our primer on Do Treadmill Desk Weight Ratings Really Matter? if you want to learn more.)

From interviews with Lifespan executives over the years we learned that the company was never really on very solid financial footing. The tariffs imposed on China only affected some of the products that Strength Master made in their Chinese factory. But the pandemic, sadly, appears to have dealt a rather significant body blow to the company. In March of 2019, insiders tell us that Schenk simply “walked away from the company.” Clearly, the Taiwanese are in charge of what remains of Lifespan Fitness now, with the daughter of Strength Master’s CEO moving to Utah to oversee the operation as its new CEO. More recently, we learned from a wave of departing employees that they were told by the company that they were all being summarily laid off, without warning, “due to covid.”

Ever since Schenk’s departure, the company’s reputation has rapidly devolved, sad to say. Many product descriptions and specifications have been dumbed down, well-hidden or completely removed from the website. There is no phone number to call (and when we called the number we had for the company we just went into a hold queue forever before being invited to leave a voicemail). Lucy the live chatbot is badly programmed and doesn’t know how to answer a single question about the treadmill desk products, only classroom products and gym equipment. The only way to communicate with the company appears to be through email, and we’ve read numerous user complaints on various networks like the BBB about customers not getting any kind of response on warranty claims and other issues. Places, that is, where Lifespan couldn’t scrub out bad reviews, as they can on their own website.

Lifespan Fitness doesn’t feel like the same company we knew so well in the formative years of the treadmill desk industry. It is sad to see what remains of its remote controlled husk today. The product offerings appear to have been thinned out and maximally cost-reduced, and the warranties have been completely removed from the treadmills. If you want a warranty on your treadmill you now have to buy it as an “extended warranty” upgrade. Calling it an “extended warranty” implies that there’s some standard manufacturer’s warranty that it is adding more years to, but there is none documented anywhere on the website any longer. What used to be the standard warranty for the first decade that these products were sold in the USA is now the minimum extended warranty you can tack on for $270.

We suppose that’s one way to keep prices down in the face of tariffs and rampant deep ocean freight cost increases since the pandemic, but we simply can’t recommend any product that has no standard warranty at all. These aren’t $20 phone chargers, they’re $1,000 – $3,000 treadmills and treadmill desks. Caveat emptor should you choose to plunk down your cold hard cash on a Lifespan Fitness product today. (Note that we do find the original TR800, TR1200 and TR5000 treadmills, in DT3 (standalone base), DT5 (with manually-fixed height setting) and DT7 (with electric height setting) still being sold on Amazon. It’s unclear whether or not these are sold with an intact manufacturer’s warranty; none is mentioned in the Amazon listings but neither are the extended warranty options. Buying through Amazon may at least give you a modicum of consumer protection if you have a problem in the first 30 days.)

Not surprisingly, Lifespan’s website traffic has also been notably degraded since the pandemic, at a time when fitness equipment, treadmill desk and standing desk categories are all booming. We used to know many of the people in the organization from trade shows and other interactions; almost to a one have moved on to other employment over the past few years. These days we learn much more about goings on at the company from departed employees than from anyone still in active management. It is a bit depressing to see the most recognized pioneer in popularizing the treadmill desk concept fall so far from its perch.

Onto the review of the TR1200-DT3 / TR1200-Glowup….

The Difference Between “Car Chassis” and “Truck Chassis”

Automotive reviews speak in terms of “car chassis” versus “truck chassis” heritage. We segregate the bottom-tier treadmills (TreadDesk, RebelDesk and Exerpeutic) from the mid- and top-tier units on a similar basis – by the quality of their components. Broadly speaking, units that sell for under $900 are generally derived from cheap, consumer-grade equipment meant to be used sparingly and for short durations throughout the week. (Ironically, the circa-2007 treadmill base used in the $4,459 Steelcase Walkstation is of the same breed.) An office treadmill is a piece of equipment you plan to use for hours most days, so you want to make sure the one you get is made from quality gear that you can rely on and be proud to own.

LifeSpan TR1200 Wheeled
Don’t sweat the weight, LifeSpan treadmills are easily moved, thanks to the rear-mounted wheels.

The original TR1200’s 131 lb. frame was substantially stronger and better made than TreadDesk’s lightweight 101 lb. frame and Rebel’s featherweight 88 lb. frame (see our review of the Rebel Desk for picture comparisons of frame construction quality). Frame flex and creaking are both problems we noticed with the Rebel, and TreadDesk has had similar problems reported. Cheapskating on the frame weight played a significant part in why those two companies are no longer around. The LifeSpan TR1200 had more metal and reinforced rectangular tubing than its cheaper competitors.

And why is this important? Rigidity is paramount in a treadmill. Excess flex in the frame can lead to early degradation of the walking deck, which leads to an increase in friction, noise, and power consumption. If allowed to go on for long enough, total motor and/or controller failure can ensue. A solid walking deck, like on the original TR1200, ensured years’ worth of walking longevity.

Unfortunately, all that changed a few years ago when the founders of Utah-based Lifespan Fitness left the company and the Taiwanese factory took over. Surreptitiously, without even changing the model names, they put all the TR Series under-desk treadmills on a weight loss program. They dropped the TR1200’s weight down from 131 to 113 lbs to save on metal and other vital components. This comports with increased reports from users about difficulty with belt tracking and other service issues since the change was made. In effect, Lifespan changed the construction grade of frame designs on the TR1200 and TR5000 from “truck chassis” to “car chassis.”

What Horsepower Means on a Treadmill Desk

As far as the TR1200 specifically is concerned, what the free market eventually revealed is what our review staff has been writing about for over a decade, that pulling a dead weight across a treadmill deck at 1-2 mph requires far more low-speed torque from a motor than when a runner is kicking the belt in the same direction the motor is turning. The force required to overcome the friction between the belt and the deck is immense, and running treadmills just aren’t geared for it. The result is always the same: premature motor failure or controller board failure. In other words, a user planning to walk at 1-2 mph should also plan to spend substantially more on a stronger motor and drive train than they would on a cardio treadmill if they want it to last. We go into the engineering reasons behind this in our primer on treadmill powertrains.

Lifespan has long been one of those treadmill manufacturers that lie about their weight ratings. There are no industry standards to speak of, so weight ratings are often what the manufacturers’ marketing departments conjure up, which is something we’ve always focused on proving in actual lab testing when we’ve reviewed these units. Rare is a company like iMovR that conducts both finite element analysis (FEA) on the design of their treadmills and months-long independent testing using specialized equipment. (And, at this point has an in-the-field record spanning many years longer than its warranty term to back up its claims.)

LifeSpan differentiates its three models by weight rating and recommended number of hours of daily use. On their own website, the TR800 Glowup is rated for 215 lbs and 3 hours of daily use; the TR1200 is rated for 350 lbs and 6 hours of daily use, and the TR5000 for 400 lbs and 9 hours of daily use. Talk about made-up-sounding numbers.

The “hours of daily use” rating has little bearing on reality. In the real world, one must account BOTH for the weight of the user(s) and the frequency of preventive maintenance. If a 175 lb. user bought a TR800 and never lubricated the deck it would eventually fail. On the other hand, a 250 lb. user who routinely sprays a little silicone oil between the deck and belt to keep their TR1200 well-lubed is going to have something that will last for many years. Better to treat the daily hour limit as a guideline rather than as a rule, though obvious differences in construction suggest the TR1200 for longer-duration usage than its little brother.

A Controller More Fit for the Gym Than the Office

Lifespan Treadmill Desk Power ConsoleThat’s how we’d describe the three LifeSpan treadmills’ controllers, which all look like they were ripped off a gym treadmill. The console is your typical treadmill brick, with a simple display and some rather unsightly membrane keys. It has all the basic functions you would expect on a treadmill. You can track distance, time, speed, calories burned, and steps taken, and a convenient USB port lets you charge your cell phone. However, the LifeSpan controller lacks the more advanced functionality users would want for their office treadmill, and the requirement of long button pressing sequences to switch display modes or restart the treadmill can get cumbersome. The controller can’t track the walking stats of more than one user, and doesn’t measure time spent off a treadmill, when you’re sitting or standing.

The controller used to have a Bluetooth sync button for uploading your stats into the LifeSpan Fitness Club Software, but it never worked correctly. Lifespan finally removed it and relabeled this controller the “Retro” style. It recently introduced a new “OmniHub” controller, which we have not yet tested in the lab, that purportedly has Bluetooth incorporated. It isn’t clear whether there’s any software to go with it, and there are no user reviews of this new controller yet, it’s that new. Users can upgrade to this new touchscreen hub for an extra $100.

Not Well-Suited for the Enterprise Environment

Enterprise customers—large corporations, government agencies, educational institutions and the like—have a particular concern with potential liability when it comes to having treadmill desks on their campuses. While this problem stems from perceptions spawned by YouTube “treadmill fail” videos and not reality (see our article on What Legal Departments Need to Know About Treadmill Desks), as the saying goes, “perception IS reality.” For this reason, the TR1200’s running treadmill-based design never had what it took to achieve widespread enterprise adoption.

While adequate, the membrane keyboard is very yesteryear. This is particularly evident in a side-by-side comparison with the touch-screen LCD display console that the ThermoTread GT offers; one that features multiple user profiles, intuitive smartphone-like features and graphics, and has a built-in “click wrap” liability waiver screen to make the corporate legal department very happy. Without this latter feature most corporate, government, and educational institutions would be loath to allow a treadmill desk on the premises, any more than they’d allow an employee to rent a car that didn’t have a liability waiver on its GPS navigation system.

The other problem with all the LifeSpan treadmill units is that their top speeds are set to 4.0 mph, far greater than the maximum recommended 2.5 mph for treadmill desk use. While attempting to capture a little more market share by allowing users to “go cardio” and sweat all over their desks, the downside is that corporate legal departments have been known to order employees to ship LifeSpan treadmills back once they learn they’ve been brought on campus. In fact, UL certification standards have changed since these units were designed a half decade ago, and they might not even pass current safety standards without some redesign.

Home users could care less, and that’s where most TR1200s are destined to be found. Enterprise users will want to veer towards the ThermoTread GT, which was designed for enterprise requirements and will satisfy the concerns of any legal or insurance expert (we’ve checked).

Why Would Anyone Need a Warranty for a Treadmill, You Ask?

If you buy a $30 electronic tchotchke you might not care a whit about whether or not it has a warranty. But a treadmill? Come on. We were absolutely floored at Lifespan’s new Taiwanese owner’s decision to eliminate the standard factory warranty from their treadmill desk products. They now offer it as an “extended” warranty, which you must buy together with your treadmill so it’s really just a scheme to make the treadmill price seem cheaper than it really is. Technically they give you 30 days the purchase date of the treadmill to add the extended warranty, but good luck finding a way to register for that warranty on their website, whether you bought it from them or on Amazon. And if you can even find their phone number (it’s not on their website anymore), good luck ever getting anyone to answer it.

We’ve read report after report of users receiving a defective treadmill and have massive frustrations trying to get Lifespan to replace it or repair it. By late 2021 we started hearing horror stories from ex-employees, too. There is no good scenario here. At a minimum, you certainly wouldn’t want to purchase a highly mechanical device like a treadmill without a warranty to back it up, so you’ll want to spring the $160 (3-year coverage) or $310 (5-year coverage) for the “extended” plan, for sure.

But the more important question is will you be able to get service when you need it? Check the 1-star reviews on Amazon (you won’t find them on Lifespan’s site where reviews are culled to keep only the positive ones) to see how many people have run into enormous challenges getting their lemons repaired.  And apparently, they’ve been shipping more lemons than ever. Sadly the brand has really gone downhill with the recent brain drain of the US staff.

In Conclusion

After ten years of recommending the TR1200-DT3 (aka TR1200 Glowup) as a very good middle-of-the-road option for the light duty profile single user, we’re saddened to have to fully revoke our endorsement for the product, and all of Lifespan Fitness’ treadmill desk products, for that matter. When company founders and people with 20 years of institutional memory all leave the company, and a foreign company takes over by remote control, bad things can happen. And that’s exactly what’s happened here. Profit margins have been squeezed and squeezed to the point that reliability is lacking and customer support is virtually non-existent. This is not trivial when you’re talking about an all-in investment of a few thousand dollars and large, heavy objects weighing hundreds of pounds that aren’t easy to return or get serviced.

Unfortunately, there aren’t a lot of alternatives in the market these days. Plenty of companies, including startups like TreadDesk, RebelDesk and UnSit, as well as large fitness equipment companies like NordicTrak, Proform and LifeFitness have made failed runs at this market, only to find out that it isn’t as easy as it looks. The torque demands on the powertrain of a treadmill desk with a user walking at 1-2 mph are far, far greater than on a cardio treadmill with someone running at 8 mph, and it’s remarkable how many engineers and marketing departments miss this little detail when they chase this market. Fifteen years after Steelcase launched this industry with the Walkstation more companies have entered the dead pool than are still producing treadmill desks. For all intents and purposes only Lifespan and iMovR remain.

As for Lifespan, the TR5000 is the next step up from the TR1200, and while the current TR5000 Glowup with its DC motor it’s dramatically less powerful than original TR5000-DT3 with its AC motor, it’s going to be marginally more reliable than the TR1200. Add the “extended” warranty on top, though, and you’re right at the same cost as an enterprise-class, bullet-proof iMovR ThermoTread GT, so you might as well go for the better unit from the more solid company at that point.

Should you DIY a treadmill desk instead? There are pluses and minuses, and should you choose to go that route there’s an entire, voluminous section of this website to help you do it, including common mistakes to avoid. We’ll just say that it’s usually a lot more complicated than people think it might be to hack a treadmill desk out of a running treadmill.  But if you’re looking for a one-and-done commercial solution, it really comes down to the TR1200 versus the ThermoTread GT.

Be sure to check out the complete round-up of lab-tested Treadmill Desk Reviews and the related round-up of Standalone Under-Desk Office Treadmill Bases. After you order your treadmill desk, but before it arrives be sure to check out our comprehensive guide on What to Expect When You’re Expecting Your First Treadmill Desk.

Recommended Accessories for Treadmill Deskers

It’s worth mentioning that iMovR’s EcoLast TreadTop Standing Mat is a must-consider add-on accessory for any office treadmill. When you want to take a pause from walking the last thing you want to do is stand on the cushion-less hard deck of a treadmill for very long, lest your feet start to suffer. These TreadTop mats are premium-quality, 100% polyurethane standing mats that are shaped specifically to fit the 20″-wide belt tracks of the most popular office treadmill models. They can be used atop the desk or astride the treadmill if you have a sit-stand-walk workstation, or both.

LifeSpan offers its own lubricant and recommends applying it to the deck after every 40 hours of use. However, we recommend the iMovR Treadmill Lubricant (100% Silicone) for its superior formulation and ease of application. See our primer on How to Lubricate A Treadmill for easy video instructions on how to keep any treadmill in tip-top running condition.

To protect your floors and your equipment, and reduce noise, static and vibration, an under-treadmill equipment mat is a great investment to consider as well. You’ll also want to check out reviews of the most stable monitor arms for treadmill desks to address one of the most important concerns of working at an active workstation, proper monitor height for avoiding the next strain.

    I contacted several LifeSpan dealers to ask them about warranty, since they still sold LifeSpan products and this didn’t add up. It turns out, in 2022, you still get full warranty when buying through a dealer. So I’d say you need to update your review to reflect that. I sent a sales lead at LifeSpan and they confirmed that there is a lifetime warranty on the frame, 3 years on motor, 2 years on parts, 1 year on labor. No extra charge for this warranty.

    • admin February 2, 2022

      Thank you, reader, for bringing this to our attention. Remarkably, it does appear, perhaps as a result of our updated reviews exposing Lifespan’s recent tactic of eliminating their factory warranties, that they have magically restored them now, to *some* degree. However, it also appears that they have at the same time raised the selling prices of their treadmills significantly to compensate for this. For example, the TR1200 Glowup was being sold last week for $1499, with an “extended warranty” of $159.99 as an add-on. That warranty is still being offered as an extension feature, but the base price of the unit has been increased by $200 to $1,699. The original warranty of 3 years on the motor, 2 years on parts and 1 year on labor has been restored on some of the units, but not all, on the website (perhaps they’re still updating their marketing information). There is a lot of fine print on the extended warranty contract, however, that the consumer should be wary of and read very carefully before purchasing. To be candid, we can’t make heads or tails out of it ( given all the carve-outs, and will need to get a legal expert to review the language before we can update our review to attempt to explain to our readers what is actually covered, and what is not. Of all the warranties we have ever seen in a decade of reviewing products (including Lifespan’s prior warranty policies) we’ve never seen one this intentionally obfuscating. Extended warranties are often scams, and this one feels pretty scammy, but it also makes some implications as to what is not covered in the *standard* factory warranty if you don’t buy it within (90) days of purchase of the unit, such as “lemon protection” and “power surge” protection”. Those should be standard features of any treadmill warranty, not honored only if you purchase an extended policy, needless to say. So, stay tuned.

    Ordered this treadmill base via LifeSpan’s Amazon in May, 2019. As expected (from reading other reviews), it came with some slight damage, but functional. The overload switch was broken and the motor cover mounting points were cracked out of the plastic cover. LifeSpan’s tech support was AWESOME. They sent me a new switch under warranty, and even though the cover was staying in place, they threw in a new cover under warranty as well. I paired this with a motorized DIY desk base, and I’m 2 days in. 11.5 hours and over 13 miles on this treadmill, and I’m loving it. I also entered the factory settings and turned off the beeping and allowed it to return to last speed after pausing. I find the base very quiet – I’ve asked 10 people if they can hear any background noise through my Bluetooth and no one can tell I’m on a treadmill. So far, I’m only going 1.2 MPH, but hoping to pick up the pace a little as I get used to typing and working. For my needs as a home office workstation, this seems to be the thing I’ve been missing all these years.

    I bought my TR1200-DT3 off of Craigslist for $500. It only had 78 miles and 48 hours on it, making it a steal, even though it had not been lubricated during it’s life. (Which I swiftly corrected!) (FYI, you can check the total number of hours and miles using the “Engineering Menu”; instructions are in the user manual; this is a boon to used buyers, and in a corporate environment where somebody needs to keep track of maintenance needs.)

    I hauled the ‘mill home in my station wagon and had my wife help me lug it upstairs. The only sign it was not new was that some of the bolts securing the side rails to the deck were loose; this was easily remedied with a wrench. A lube, and a little tweaking with an allen wrench to center the belt and I was good to go!

    Setup was easy, and I swiftly used the Engineering Settings to turn off the beeping and the “pause when stepping off for 30 sec.” option. (I work from home, so this is not an issue.) While my version of the console (an older one from a couple years back) does not have the ability to do this, you can also tell it to pick up at the speed at which you last paused it. This is not a good idea in a corporate environment, but it’s great for a home office.

    I sent Lifespan a question about the motor and maintenance instructions, and while it took them a day, they responded with full answers to my questions, even though I had made it clear I had purchased an older unit on the used market.

    I’ve only been using it a couple weeks, and I’ve already put 60 miles on it! Even after 3 hours of non-stop use, the motor is merely warm to the touch, and the motor control board is cool to the touch. I’ve been maxing out the six hours a day, with the only ill-effects to my slightly tired feet! The treadmill doesn’t mind at all!

    The review has a minor error: There IS a feature to limit the top speed of the treadmill (to 2MPH) if desired. Maybe this review was correct when written, but this is no longer the case.

      One more thing: I forgot to mention it in my review, but I haven’t had any major issues with the Android App / Bluetooth. Sometimes it does not connect, but terminating the app (with a simple swipe in the app switcher) seems to fix it without an issue.

      The “LifeSpan Fitness Club” website will also upload your results to Google Fit, which is nice. I kind of ignore the website otherwise; it’s a bit kludge-y and clearly designed as some sort of overall corporate fitness-promoting app, which is a bit of overkill for a single home user just trying to track their treadmill use. The Android App is much nicer (no experience with the iOS version…)
