The Xebex Runner is a motorless curved treadmill. It doesn't use electricity and instead works with the energy produced by the user's own movement. Beginners and competitors can run at the desired speed and change it at will without any maximum or minimum speed settings. 

Built with HIIT (High Intensity Interval Training) in mind, the Xebex Runner dial keeps you informed of your time, calories burned, distance, speed, watts and pace. It has several heart rate and interval programs available.
