HOW: Begin this exercise by finding a comfortable step height for you. With the step in front of you, step back into a reverse lunge with one leg then push up through the front leg and use that back leg to step up onto the step. Finish the exercise by driving the other knee up into a standing march position.
FEEL: You should feel your hip muscles and core muscles engage as you perform this exercise.
COMPENSATION: Avoid allowing the knee of the front leg to fall excessively inward as you step back into the reverse lunge. Maintain a strong base of support.
