The LifeSpan TR1200-DT3 is our top selling walking desk treadmill base and console, designed to support single users or small teams.

The compact treadmill fits under standing desks, making it easy to convert your standing desk into a treadmill desk.

Upgrades from the TR800-DT3 include a larger motor, 2” wider walking belt and a low-profile design.

The portable console is small enough to fit discretely on your desktop and still provide all the features you need, including readouts for steps, time, distance, calories and speed.

The TR1200-DT3 walking treadmill is durable enough to share with coworkers and quiet enough to keep it all to yourself.


Refined, contemporary design and long-lasting construction make the TR1200-DT3 the perfect addition to your office. Quiet operation lets you stay respectful of coworkers while you walk for miles each day without impacting productivity. High-quality components suppress mechanical noise and subdue vibration, keeping your focus on the task at hand.

The compact under-desk treadmill guarantees a perfect fit and easy placement under your standing desk. Since the step-up height of the walking desk treadmill will take from the available height range of your standing desk, the low 4.6? height will help you get the optimal ergonomic position from your desk.
