Equipped with unique, shock absorbing flexible slats that reduce joint impact and discomfort.

Designed for HIIT Training, Interval Training, Sprints, Short Distances and Walking. This treadmill is not recommended for long distance running as the flexible slats increase the intensity of the workout.
