HOW: Stand in front of an elevated surface. Begin the exercise by stepping up onto the elevated surface and over and beyond the other foot (if stepping up with the left, place the left foot to the right of your right foot). Stand tall on the elevated surface with both feet, return to starting position and repeat.
FEEL: You should feel your hip and thigh muscles on the leg that you're stepping up on, especially the muscles on the outside and back of your hip working.
COMPENSATION: Maintain good trunk control, control the movement and don't take advantage of momentum to step up. Do not lean excessively forward or side-to-side
