LifeSpan Fitness TR5000-DT3


Review Summary

If comparing to the two weaker treadmill base models from Lifespan (the TR1000 and TR1200), the TR5000 is the most reliable and durable. But that’s not saying much in comparison to what it used to be before Lifespan quietly gutted its design without so much as changing the model number. They removed the powerful AC motor and replaced it with a much cheaper and less bulletproof DC motor, and they reduced costs further by thinning down the steel frame and lowering component quality as they did with the other models. Concerns about the company’s change of control and management team “brain drain” give us pause, as do the common customer complaints about warranty service response time and the deficiencies in the controllers and smartphone app. Still, of the few office treadmill bases left in the market today the TR5000 technically has the strongest power train. But with these upgrades over the other Lifespan units the price of the TR5000 gets so close to the competition that many users will pay only a small increment more to go with a better brand like Unsit.

Positives The most powerful in the line-up of three under desk treadmill base models Lifespan offers, the TR5000 features upgrades over the TR1200 like a 3.0 HP DC motor, a 1"-thick walking deck, aluminum side rails and a heavier-duty walking belt. The 20"x50" deck means it may be more comfortable for very tall users as compared to the Unsit's 30"x40" deck, despite the TR5000 having 50% less overall usable walking area.
Negatives A few years ago Lifespan gutted out the TR5000 without changing the model name. This used to a be a "Sherman Tank" of a treadmill base built around a bullet-proof AC motor, but users hated how noisy it was. It also consumed huge amounts of electricity. It is now only slightly more robust than the TR1200.

Bottom Line

The TR5000 is the most powerful and therefore most reliable of Lifespan's three office treadmill models with a 3.0 HP DC motor, and relative to the other three thinned-down units, the one with the heaviest frame at 119 lbs, heaviest deck at 1" thickness, and most durable walking belt and side rails. Lifespan rates it at "9 hours a day" duty cycle, which is really a contrived marketing positioning stunt. There have been some concerning developments at the company in recent years (read the review below), but if looking past those issues, the TR5000 is likely to be more trouble-free than the TR1000 and TR1200. That said, the controller, Bluetooth and smartphone app deficiencies will be exactly the same, since both the Retro and Omni Hub controllers work exactly the same on all three units.

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 (discontinued and replaced with the newer TR1000-DT3) and the heavy-duty TR5000-DT3 reviewed here, 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. In 2015 iMovR launched the first 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, giving Lifespan its first real competition. In 2022 iMovR ended production of the ThermoTread GT due to supply chain challenges and partnered instead with another competitor, InMovement, to bring out the iMovR Unsit treadmill base.

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 removed entirely from the Lifespan website at one point, though they appear to have recently returned.

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 on the models using the old-school DT5 and DT7 desk bases.

lifespan standing desk review

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 curves our spines 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 TR5000-DT3 is now the TR5000-Glowup. 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 had always been 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?)

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. TR1200 and the 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,” purportedly after some internal scandal over nepotism. Clearly, the Taiwanese are in charge of Lifespan Fitness today, with the daughter of Strength Master’s CEO moving to Utah to oversee the operation as its new CEO. In 2019, 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 taken a bit of a hit, sad to say. Many product descriptions, detail photos and specifications have been dumbed down, well-hidden or completely removed from the website. It’s sometimes hard to get a human on the phone. 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. 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 most of the bad reviews (to be fair, most manufacturers do the same). Despite assurances to the contrary from the new management, Lifespan Fitness doesn’t feel like the same company we knew so well in the formative years of the treadmill desk industry.

Onto the review of the TR5000-DT3 / TR5000-Glowup….

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

Automotive reviews speak in terms of “car chassis” versus “truck chassis” heritage. The other two remaining Lifespan treadmill desk models (TR1000 and TR1200) are “car chassis” frames that are light on the steel, less rigid, and thus subject to a lot of annoying issues like belt drift and squeaking coming from the frame as you walk. Typical of low-cost “consumer grade” treadmills.

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

The original TR5000’s 145 lb. frame was substantially stronger and better made than the cheaper units, and combined with the strong AC motor made it a “truck chassis” unit. 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 TR5000, 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 TR5000’s weight down from 145 to 119 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 design on the TR5000 from “truck chassis” to “car chassis.” While it used to be comparable to the enterprise-grade ThermoTread GT with its 150-lbs frame or the Unsit with its 162-lbs frame—both with 24×7 duty cycles—the TR5000 is now decidedly no longer in that same heavy-duty class of treadmill bases. It is off with all the other consumer-grade treadmills that Lifespan sells.

The original TR5000 also used a double-sided deck, which meant that when it wears out on one side it could be flipped over to get an extra life out of it. The walking belt they used to ship with the unit was self-lubricating, while the new design uses only what Lifespan calls a “heavier duty” belt as compared to the one used on the TR1200 and TR1000.

The one positive of the change to a DC motor is that the power consumption came down by about half, and the wearisome noise coming from the fan in the AC inverter on the older design is gone now.

This reduction in component durability means the TR5000 is no longer recommended for multi-user environments. Whereas it used to be one of the two go-to machines for corporate, government and education accounts, it’s pretty much designated for home office use only now.

What Horsepower Means on a Treadmill Desk

As far as the TR5000 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.

LifeSpan differentiates its three models by weight rating and recommended number of hours of daily use. On their own website, the TR800 Glowup was rated for 215 lbs and 3 hours of daily use; the TR1000 and TR1200 are rated for 350 lbs and 6 hours of daily use, and the TR5000 for 400 lbs and 9 hours of daily use. 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. According to treadmill engineers on our staff there is no direct correlation between hours of continuous use and the capabilities of the powertrain; this seems to have been a ploy devised by Lifespan’s marketing team to guide consumers up to higher priced units if the machines were going to be heavily used.

A Controller More Fit for the Gym Than the Office

LifeSpan Fitness TR5000-DT3

That’s how we’d describe the aesthetics and haptics of the desktop controllers Lifespan puts on their office treadmill bases. The “Retro” console, which has been the most commonly sold since the inception of these under-desk treadmill bases more than a decade ago, is your typical desktop brick. It has a simple LED display and “bumpy” membrane buttons, and has all the basic functions you would expect on a treadmill. You can track distance, time, speed, calories burned, and steps taken. It even has a convenient USB port on the back that 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.

For an extra $100 you can upgrade from the “Retro” brick-style controller to the new “Omni Hub Smart Control” with a bigger LCD screen and Bluetooth

The original desktop brick 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. They recently introduced a new “Omni Hub Smart Console” controller, which we have not yet tested in the lab, that purportedly has Bluetooth incorporated. Users can upgrade to this new controller for an extra $100 when buying a treadmill base, or pay $299 to upgrade their existing Retro controller. The OmniHub isn’t a touchscreen but it does feature a larger LCD screen and gym style buttons beneath it. And it has a Bluetooth interface.

lifespan fitness app review ⁣While the new Omni Hub Smart Console has a Bluetooth interface, the Lifespan Club app leaves a lot to be desired, and isn’t going to be particularly useful in the treadmill desking application.

Lifespan Fitness in Utah itself does not employ any full-time engineers; the real engineers are all back in Taiwan. This has led to very long-standing problems with some features, especially those surrounding Bluetooth and the smartphone app. The app is really the generic “LifeSpan Club” app that was built around all their gym equipment, not one specifically designed for the needs of the office treadmill user. And at that, it garners all of a 1.2-star rating out of 5, with some pretty harsh reviews.

A recent 1-star user review sums it up pretty well, saying “This app is terrible and many steps backward from the prior version. Aside from the cumbersome setup, many of the instructions are not in English and can’t be changed to English. Also units of measure are inconsistent between metric and imperial so you constantly have to calculate between metric and imperial when entering data….” it gets worse from there. This user added an update, saying “it’s been months since my review and the app still does not work. I’ve contacted support numerous times and the company seems unmotivated to either fix this app or return the old app that worked perfectly. I wish I could return this treadmill and get a competitor product. This company is unfazed by their low quality and user feedback.”

So while the new Omni Hub “Smart Console” is a little easier to use (we especially like the three speed preset buttons, which eliminates the many button taps it takes to restore you favorite speed when using the Retro controller), the Bluetooth feature and related smartphone app seems to be as broken as ever.

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 buttons on the Retro console is very yesteryear. This is particularly evident in a side-by-side comparison with the touch-screen LCD display console that the ThermoTread GT offered; 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 TR5000s are destined to be found. This is evidenced, if nothing else, by the fact that all the shipping options are described as “to your residence.”

In Conclusion

After ten years of recommending the TR5000-DT3 (aka TR5000 Glowup) as a heavy-duty treadmill base for multi-user workstations, we’re saddened to see the drastically downgraded quality of its components and the long-standing engineering problems with the Lifespan Club app. When company founders and people with 20 years of institutional memory all leave the company, and the manufacturer all the way in Asia takes over management, bad things can happen.

The issues raised in many user complaints that you won’t find so prominently within Lifespan’s curated users reviews, but you will find on Reddit, BBB, the App Store and other independent sources leave us quite concerned. These issues are not trivial when you’re talking about an all-in investment of a few thousand dollars, and large, heavy objects that aren’t easy to ship back or get serviced. Removing ones that related to shipping failures (freight carriers are notorious for these, and they’re not Lifespan’s fault in general) of the remaining complaints most seem to be about reliability/service, and frustration over the user interface with the Retro controller or Bluetooth and software app frustrations with the Omni Hub.

Unfortunately, there aren’t a lot of alternatives in the market these days. Plenty of companies, including startups like TreadDesk and RebelDesk, 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/Unsit remain.

As for Lifespan, the TR5000 is the next step up from the TR1200, and while the current TR5000 Glowup with its DC motor is dramatically less powerful than original TR5000-DT3 with its AC motor, it’s going to be empirically more reliable than the TR1200. That said, the price gets pretty close to the Unsit treadmill base at that point. We generally rate the Unsit much higher than the TR-series from Lifespan, with one caveat: The longer deck on the TR units are advantageous for very tall users who have a longer stride length and for multi-user workstations where users of mixed stature would be sharing the equipment. The Unsit, on the other hand, has 50% more usable walking area, is far quieter, has a working Bluetooth link and smartphone app, and takes up a lot less floor space in your office.

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.

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.

If you don’t have a large enough standing desk to accommodate both the treadmill and an office chair, definitely check out our round-up of the best treadtop seats for treadmill desk users.

After you buy a standing desk or treadmill, you might also need to get rid of your old office furniture. So, make sure to read our primer on the best ways to get rid of your old desk or treadmill.

    It is simply not true that these are just re-skinned running treadmills. In addition to the console being different (obviously), they DO have different motors and pulleys vs. their running counterparts. (This is patently obvious if you look at pictures of, say, the TR1200i motor vs. the one in the TR1200-DTx) And if you ask LifeSpan about turning a 1200i into a desk treadmill, they will say the same thing.

    And, funny how you left out a mention of the fact that the 5000, with an AC-based drivetrain, means longer motor life, longer motor-control-board life, and no wear-part motor brushes vs. DC-motor based units. All you did was point out the downsides (mainly the noise of the inverter fan and increased power load.)

    Also, your “reviews” would be a lot more ethical if you disclosed the fact that you are owned by iMovr in your reviews of competing products. While you meet the “letter of the law” by disclosing the relationship in reviews of your own products, it certainly violates the spirit of the law to not mention the relationship when constantly mentioning your products in the reviews of the competition.

    Lastly, the console firmware has been updated (two years ago, I think) to be able to limit the top speed of the units to 2MPH if desired. (You can also shut off the console beep, and tell the unit to pick up where it left off, speed wise, if you desire.)

    And no, I don’t work for LifeSpan (or any fitness or office equipment dealer), I’m just a happy 1200-DT3 owner.

      My 5000 had a DC motor, not AC.

      • admin April 25, 2023

        Yeah, that’s their reworked model. Kind of slimy to change all the specs on a product and keep the same model number. They could have easily renamed it.

  • Ryan Dietrich March 3, 2015

    Stunningly awesome device. I bought mine on amazon, you can check out my review there. It does not flex, it does not do anything that it should not do. The base station that sits on my desk is awesome. It just works. I use it between 4-6 hours a day. I lubricate it once a week. I love it. It was a little expensive, but it’s worth every penny. The software is a little weird but I got it set up on my laptop, sending my stats to their website. Cool to be able to track your progress, makes it a little more fun.

    For anyone on the fence between the various price levels. The cheaper models are going to have more issues, if you’re willing to make that trade, that’s fine. But if you only want to spend the money once, get this one, it is worth it.

    I got it in the sale for £2500 (£500 off rrp) and I know that’s steep but I work from home and figured that it’s a small price to pay for my health. I’ve spent plenty of money over the years on gyms (which I rarely attend) and other fitness equipment and saw no benefit, admittedly mostly due to my own laziness. The Lifepsan Treadmill desk is a whole different experience. It doesn’t feel like exercise at all. I have to work at a desk 8 hours a day anyway so why not walk at the same time, and working whilst I walk means I’ve knocked up miles without even realising. It’s a doddle to get used to walking and typing. The desk raises to the perfect height to rest my wrists on so my hands don’t really move, just the rest of me. I start the morning at 1mph then quickly move to 1.5 and the 2.0mph. 1.5mph is the best speed for me to take voice calls on. I don’t get out of breath at all and people have no idea i’m walking whilst i talk. I always use hands-free kits. If i need to concentrate I can lean forward on the desk (to stare with intent and whatever I need to concentrate on) and carry on walking. When i’m just reading or responding to email I often up to the speed to 2.5mph which is a bit more of a “power walk” but it’s still easy to type and be productive.
    I should say I purchased 2 commercial grade monitor mounts that I’ve attached to the desk so my 2 ultra wide 29 inch screens are always at eye level. This means my posture is so much better as has my lower back strength. Just sitting a regular monitor on the desk wouldn’t be high enough for me. Also having mounts means I free up loads of desk space. I have an open work laptop under on of the screens so I effectively have 2 works screens. I also have a second personal closed laptop on the very handy shelf just under the desk. I also have 2 wireless mice and keyboards on the desk and still have two thirds of the desk space empty for phones, drinks, papers etc. (I work in IT hence the plethora of equipment).
    I can’t rave about this treadmill desk enough. When I’m at home I can easily do 8 miles a day and burn over 800 calories. I’ve never got on with exercise and this doesn’t feel like exercise which is why I love it. Offices everywhere should have them and here in the UK there are several enterprises and government agencies that have cottoned on to this and have starting installing them already.
    The only (slightly) negative thing I have to say is about it is regarding the Treadmill Desk App. It’s a bit fiddly to get used with the bluetooth syncing and if you stop (not pause) the treadmill the counters reset to zero. This also happens if you pause and the treadmill goes into sleep mode. The desk itself does not hold on to the data and neither does the app so you end up with multiple data sets rather than a single cumulative one, which is what I really want to see. Maybe there will be an update that gives you the option to store data cumulatively for a certain time period …. but even if not I’d still buy one of these again in a heartbeat. It’s easy exercise for the lazy !!

    Well, I returned mine.

    So this is far more a review of Lifespan and their horrible customer service than it is of the treadmill.

    I ordered a TR5000-DT3 to go with a Next Desk Terra Pro, because I’m a bit on the large size. (6’4″,250 lbs)

    Unfortunately, I accepted my treadmill with a box with “warehouse rash”, and when I opened it, it had obviously been dropped on a corner at some point during shipping.

    The wheel on the front was shattered, the frame was bent, and the right extrusion arm was pushed slightly out of place. However, the treadmill was still functional.

    Not the end of the world. I received contacted the company, and received instructions to email pictures of the damage back to lifespan (PCE Fitness). I email the pictures back in and waited for lifespan to get back in touch with me. A week later, I again got in touch with lifespan, and arranged for what I thought was a replacement. I followed up to ask them about the replacement process. 15 days later, still no replies.

    For a $2000 treadmill I’d expect better service.

    I did setup the treadmill while I was waiting during my interaction with customer service.

    The treadmill itself was not that impressive. The belt started slipping after a week, and the treadmill did not automatically enter sleep mode. After stopping the treadmill I had to hold the stop/pause button until it reset in order to get the treadmill to enter sleep mode. If I did not do this or pull or the safety key the fan on the treadmill ran indefinitely. Not really a deal breaker, just annoying.
