Lie on your right side with your knees straight, feet stacked. Prop your upper body up on your right elbow and forearm. Raise your hips until your body forms a straight line from your ankles to your shoulders, and place your left hand behind your head.
Slowly lower your right hip to the floor as you rotate your left elbow down to your right hand. Lightly tap your right hip on the floor (don’t sit on it) and then lift back up as you open your elbow up and return to your starting position. That's one rep. Do 15 reps on the right, 15 on the left.
