1. Place your right foot flat on the step, and your left foot flat on the floor.
2. Exhale and push off as little as possible with the left foot as you bring it up to step level (you'll now have two feet on the step). Please note, the right leg performs all the work.
3. Inhale and return your left foot to the floor, and repeat with same leg.
4. Complete all repetitions with the left foot going up and down, then repeat with the legs reversed.
Repetitions: 10 to 20 on each side or to muscle fatigue.
