TR1200-DT5 Frame

The LifeSpan TR1200-DT5 features a steel frame coated with a corrosion-resistant paint finish. The colors used are gray for the desk frame and black for the base frame of the deck. The deck comes with adjustable, rubberized stabilizers at the back and has two transport wheels at the front, facilitating its relocation if needed.

The treadmill integrates a durable, 3/4″ phenolic deck, supporting users up to 350 lbs (158.7 kg). Thus, it is pretty impressive for a walking treadmill. The cover of the motor and the deck’s side rails are made of ABS material, though. The side rails also have a non-slip surface.

The unit’s tread belt offers a walking surface of 50″L x 20″W (127 x 51 cm), which is more than enough for users up to 6’5″ (196 cm). In addition, it’s a 2-ply rubber belt that provides superior adherence.

The assembled unit is relatively large. Its overall length is 68.5 (174 cm), while its width is 38″ (96.5 cm). Therefore, it’s advisable to assign at least one foot of clearance on each side and at least two feet at the rear for safe operation.

This LifeSpan desk treadmill doesn’t have a folding design. The deck can be easily removed from under the desk, though, and stored under a bed, for example.

In addition, this treadmill doesn’t have an incline system. Also, the height of the walking belt is pretty close to the floor. Therefore, the unit’s step-up height is approx — 4.6″ (11.6 cm).

An essential aspect of the unit’s deck construction is shock absorption technology. The deck integrates six independent compression shocks, reducing the cadence’s sound and vibration and the overall walking impact on the joints.

In other words, walking on this treadmill will produce less joint pain than walking on asphalt or concrete.

Last but not least, the deck is relatively heavy. It weighs approx — 114 lbs (51.7 kg). However, its relocation or attachment to the desk is more accessible due to the integrated transport wheels.

Intelli-Step™ and Intelli-Guard™

Two other notable features regarding this treadmill are the Intelli-Step™ and Intelli-Guard™ features. Intelli-Step™, as its name suggests, is a step-counting feature with a sensor that can count every step you take.

Intelli-Guard™ is a feature in several other LifeSpan treadmills, such as the LifeSpan TR3000i. It’s a safety feature that automatically stops the belt when you are no longer walking.

TR1200-DT5 Desk

The desk of the LifeSpan TR1200-DT5 features a steel frame just like the deck. Its height is adjustable, offering multiple adjustment positions. The minimum size is 33.5″ (85 cm), while its highest position is 52.5″ (133.5 cm). The desk’s height adjustment is via the two knobs on each one of the upright posts.

Each base of the desk frame features a small adjustable stabilizer on its front part. Therefore, you should level the unit on any flooring perfectly.

The desktop surface has a 1″ (2.5 cm) thick HD composite material and durable laminate. It’s 29″ (73.6 cm) deep and 38″ (96.5 cm) wide. Thus, it’s large enough to accommodate your laptop and even a 2-monitor setup. In addition, its front part also features a cable management compartment.

The structure of the desk is not extremely heavy. It weighs approx — 60 lbs (27 kg). Therefore, its relocation or assembly shouldn’t be a problem for one person.

TR1200-DT5 Console

Like any other treadmill, the LifeSpan TR1200-DT5 has a fitness monitor. It integrates into the desktop. It features a small LCD with an LED backlight and relatively significant digits.

It tracks time, distance, speed, and calories burned. In addition, as I’ve mentioned above, the machine has the Intelli-Step™ feature, which counts your steps as you walk.

This monitor does not have a pulse reading function. Therefore, if you need to keep an eye on your pulse during exercising, you must use a separate device. The speed and distance are in either standard or metric units.

Unfortunately, there are no pre-set workout programs in the unit’s memory. However, it is Bluetooth enabled and compatible with the free LifeSpan Active Trac app, available for Apple OS and Android systems. In addition, you can sync your device with the monitor to directly stream your workout data online and keep an eye on your progress.

The monitor is relatively easy to use. It has a SCAN function that rotates all the workout metrics showing each one for several seconds. The SCAN mode is disabled via the Change Display button. The unit’s speed is adjustable via the arrow keys on the right.

The Stop / Start buttons allow you to quickly pause and resume your workout if necessary, while the Stop button also covers the unit’s reset function. Like all other treadmills, this one also has a magnetic safety key. And finally, the Bluetooth feature has a button.


The LifeSpan TR1200-DT5 treadmill comes with a 2.25 HP High Torque Continuous Duty DC, heavy-duty motor. It delivers speeds up to 4.0 MPH (6.4 km/h), the starting speed of the belt being 0.4 MPH (0.64 km/h). The motor is powerful enough to deliver optimal performance for prolonged use, even if the user is close to the 350 lbs weight limit.

The speed adjustment increments are 0.1 MPH, allowing you to quickly find the perfect pace for your height or workout.

The motor is whisper-quiet, allowing you to be respectful toward your coworkers while you walk for miles each day without impacting office productivity. On top of that, the deck’s high-quality internal components suppress mechanical noise and subdue vibration, keeping your focus on the task at hand.

TR1200-DT5 Assembly and Maintenance

The treadmill part comes pre-assembled. So, the only thing that requires assembly is the desk. Consequently, it shouldn’t take more than 20-30 minutes. Once completed, all you have to do is attach the treadmill in-between its bases—the tools required for the assembly of the desk come included, and the manual provides precise assembly instructions.

Like any other treadmill, the primary maintenance aspect is the lubrication of the belt. Therefore, it is required to use the silicone-based lubricant periodically. Other than that, it’s advisable to regularly check the machine’s integrity, re-tighten any loose bolts, etc.

  1. I work online, so most of the time I am sitting on a chair all day. I have different physical problems, like back pain, knee pain, etc. My doctor asked me to do physical exercise. But where is the time! So I was thinking the last few weeks-what shall I do! But after reading this review it sounds like the perfect solution. I think now I can look after both my physical health and business at the same time. And in this review, you explain everything very well that I didn’t have any problem making a buying decision. Thanks a lot.

  2. Thanks for your thoroughly informative post on this treadmill workstation. Reading it the first thing that came to mind for me was that it’s a great idea but what about the cost? I was pleasantly surprised to see that this products doesn’t cost the earth. My goal is to be a full-time writer and a downside of that is  that for most of the day I will be sitting on my butt and I don’t have the kind of metabolism that does well with that, so this will be a great idea for me. Do you have any suggestions about how you train yourself to focus on work and walk at the same time? I imagine it would take a little getting used to?

    • Hi Deb, I faced the same problem of sitting all day. This has been a lifesaver for me. It took me a little time to get used to walking and working at the same time but after a while, you’ll get used to it.

  3. I always make sure to do my daily workout but sometimes its difficult to keep up because of work, now stumbling on this post is really amazing and the TR1200-DT5 will really be useful for me because I can work and I can still workout at the same time. I like the spec of the treadmill and its durability is topnotch. I’ll make sure I get one as soon as possible. Thanks for sharing this informative and useful article, it’s really nice.

  4. Hello Robert,
    I love the LifeSpan TR-1200-DT5 treadmill writer is ideal for me. I work many hours a day sitting on my computer. My body due to the sitting all day I begin to feel discomfort in legs and back. 

    I think that the capability of this product would be the solution to all my physical discomfort.  

    Thank you! Claudio
