Here is a treadmill that lets you keep your legs moving while sitting. The HomeTrack Sitting Manual Treadmill is perfect for those recovering from injury or dealing with bone/joint conditions. It has a 2″ screen to show calories count, time, and steps. Its suction feet prevent floor scratches and make sure the treadmill stays put.
You can adjust the incline using the back legs. The HomeTrack Treadmill is compact enough to easily fit under your desk.
