The Stroops Optimill® is a one-of-a-kind design of motorless treadmill built to give you the most authentic experience possible. With the Optimill®, you don’t just feel like you’re running, you actually are.

When using a conventional treadmill, runners miss out on the important exertion of driving into the ground and forward with their foot. With the Optimill®, this part of running is essential to operating the machine. The Optimill® is motorless and is driven forward by the force of your foot while your body is held in place by a shock-absorbent Slastix resistance band attached to a steel spine.

While running on the Optimill®, the wireless Polar HR monitor mounted in front helps you track your speed in real time, along with your heart rate, distance, and more.
