The perfect indoor running experience.

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.

Confidence in safety.

The Optimill® is the perfect solution for the safety issues that surround conventional treadmills. Nearly 25,000 injuries are reported from treadmill use annually, many of them due to the inability to organically stop or slow movement.

With the Optimill®, you can’t be outpaced by the motor—because you ARE the motor. The belt of the Optimill® is made with shock-absorbent slats to significantly reduce stress on your joints. Its smooth motion is powered by your pace, slowing and stopping at the same time as you. The strap holding you in place is also designed for shock-absorbency with our Slastix resistance band technology.

Versatile training potential.

The Optimill® is a premium running solution no matter what your fitness level, since the speed of the treadmill is determined directly by you and not by a motor. High-performance athletes and rehab patients alike have benefitted from its use.

Using the Optimill® with other equipment, you can vary the resistance when you run by strapping in by your shoulders, waist, or chest. You can even operate the Optimill® while the strap is on a wrist or ankle to help with gait correction.

The design of the Optimill® keeps it low-profile and far easier in terms of portability than conventional treadmills. Weighing only 220 pounds—50 pounds lighter than the average treadmill—the Optimill® is capable of easy movement so you can set it up anywhere.

Combine the Optimill® with the Movement Optimizer Rehabilitation Frame to create the most universal experience in movement rehab ever.
