Place forefeet into pedals. Squat down and position shoulders forward in padded yoke. Grasp handles to sides. Push one pedal back by extending knee and hip so one leg is straight while the other remains forward.
Push forward pedal back by extending leg while allowing other pedal to come forward by bending opposite leg. Continue pedalling by alternating between sides.
Adjust yoke position to accommodate near full range of motion without forcing hips to bend at waist. Also see Lever Sprint Machine.
