HOW: Begin in a high plank position with a band around your forearms. Bring out your arm and leg on the same side, allow the opposite side to follow up towards that side and repeat.
REGRESSION: If too difficult perform this exercise on an elevated surface or with your knees on the floor. Both of these variations will decrease the demand of this exercise.
FEEL: The muscles in the shoulders in addition to the core will be working with this exercise.
COMPENSATIONS: Avoid moving your pelvis from rotating as you bring out your arm and leg.
