TR1200-DT3 Frame Construction
The LifeSpan TR1200-DT3 treadmill has a steel frame coated with a corrosion-resistant black paint finish. Of course, the machine also integrates several parts made from thermoplastic material. The most notable ones are the motor cover and the side rail covers.
The treadmill is smaller than the TR1200-DT5, even though they have the same walking surface. The DT3 model is only 63″ (160 cm) long and 28.5″ (72 cm) wide, so it fits under most standard desks. It is also advisable to allow at least two feet of clearance on each side of the deck, and at least three feet at its rear, for unhindered usage.
Although it’s not a standard treadmill and lacks the front upright supporting bars for the console, the TR1200-DT3 is relatively heavy. Its net weight is 119 lbs (54 kg). Therefore two people should transport the packaged unit. However, once unboxed, one person can quickly move the treadmill as its front base integrates a set of transport wheels.
Last but not least, this treadmill rests on four adjustable levelers. In addition, they have large rubber pads for an improved grip on the floor.
The LifeSpan TR1200-DT3 treadmill features a cushioned deck. It integrates six shock absorption elements which considerably reduce the impact of the ride. The side rail partially conceals the shock absorption elements. They are non-adjustable.
The machine comes equipped with a 3/4″ (1.9 cm) phenolic deck. Therefore, the internal deck board is pretty sturdy but also has a bit of flex which adds to the overall shock absorption of the ride. The treadmill has a maximum user weight limit of 350 lbs (159 kg) which is not bad for a non-commercial machine.
The LifeSpan TR1200-DT3 offers a pretty sizeable walking surface for an under-desk treadmill. It is 50″ (127 cm) long and 20″ (51 cm) wide, while similar models only offer a 40″L x 15″W (101 x 38 cm) active area. In addition, the belt comes multi-layered with a rubberized top layer, improving grip.
The internal rollers are smaller in diameter than the rollers of the average running treadmill. The front tapered roller is 2.4″ (6 cm) in diameter, while the rear tapered roller is 2.0″ (5 cm). As a result, they provide superior traction and prolong the belt’s life span.
This treadmill does not have an incline system. Its step-up height is 4.6″ (11.6 cm). Thus, there shouldn’t be any ceiling height issues. However, it is advisable to place and use this machine in a room with a ceiling at least 10″ (25 cm) higher than the tallest user’s height.
TR1200-DT3 Drive motor
The LifeSpan TR1200-DT3 is an electric, motorized treadmill. Thus, it requires an external power source. It comes with a power cord featuring a 3-prong US standard plug mounted to the machine’s front base section, next to an On/Off switch.
The treadmill comes equipped with a 2.25 HP motor to withstand prolonged workouts. It is powerful enough to support 350 lbs (159 kg) users without overheating or losing performance. It also integrates a small flywheel which improves its overall motion stability.
The machine’s motor offers a speed range between 0.4 and 4.0 MPH. Accordingly, it’s a treadmill for walking, but you can also perform a light jog or a power walk at 4.0 MPH. The speed increments are 0.1 MPH, so you can quickly adapt your pace when making adjustments.
The console features arrow (Up, Down) controls for gradual speed adjustment. When using these, the speed adjusts in increments of 0.1 MPH. However, the console also has a Preset button, setting up a custom speed for quick selection. The default preset speed is 1.5 MPH.
The machine’s motor is pretty quiet. Therefore, the treadmill is perfect for an office environment. However, depending on the user’s weight, walking technique, footwear, and other factors, their cadence may generate more or less noise.
The LifeSpan TR1200-DT3 comes equipped with a pretty simple console. It’s not incorporated into the machine, as is the case for other under-desk treadmills. Instead, it is attached to the treadmill via a power cord and placed on a desk.
Nevertheless, if you’re not going to use the treadmill while working at a desk, you can set the console at the front of the machine.
The console unit features a LED display that tracks time, steps, calories, distance, and speed. By default, the speed and distance are in Imperial units (MPH and miles), but it is possible to change them to metric units.
Unfortunately, the treadmill does not have a pulse reading function; it will not read your pulse from a wireless transmitter.
The console does not have preset workout programs or Bluetooth connectivity. It also isn’t compatible with any fitness apps. However, it is pretty easy to use. It has five buttons. These are Start/On, Stop/Reset, Preset, Up, Down, and Enter/Mode.
The Start/On button is the power on button. The Stop/Reset button allows you to pause the belt or reset the values on the LCD. Finally, the Preset button allows a custom speed between 0.4 MPH and 4.0 MPH for quick selection.
From the Up/Down arrows, you can increase and decrease the speed. And finally, the Enter/Mode button allows you to scroll through the workout metrics or confirm the desired preset speed.
TR1200-DT3 Assembly and Maintenance
Like many other under-desk treadmills, the TR1200-DT3 doesn’t require any assembly. All you have to do is remove it from the box, connect the power cord and the console, and the machine is ready to use.
For maintenance, the belt requires lubrication after every 50 hours of use. It comes pre-lubricated from the factory and shouldn’t need lubrication before the first use. It would help if you kept the machine clean, especially the belt, to prevent debris or textile fibers from being caught in the motor or the rollers.

Thank you for an in-depth review on LifeSpan TR1200-DT3 Under Desk Treadmill | Get Fit While You Work.
I am interested in this treadmill. It is the perfect way to get some of your daily steps in, primarily if you work a typical 9-5 job where you sit behind a desk the whole day, and with the low noise level, you don’t have to worry about bothering any co workers while you get some exercise.

Hi Robert, your review of the under desk treadmill gives us all we need to know about this particular treadmill. I didn’t know of this type of treadmill. It is most interesting that a treadmill is now easy to assemble and dismantle and fits in smaller spaces at home. The convenience of having such equipment does not allow for any excuses anymore that there is no time to exercise. I would say “wow,” and thank you for sharing this article/review.

This equipment seems perfect for a work-from-home type setting. I am not sure working out while you work would be conducive to a productive work environment. The concept, at first glance, seems doable, but after further review and consideration, I am not so sure. The equipment, however, appears to be a standard treadmill minus the typical upright handles with a control panel. I think the target audience for this type of equipment would be limited. Still an interesting concept. Thank you.
