The stability ball makes you stabilize from side to side. Once you have found your position and feel stable, lift your torso up until it is in line with your lower body using your lower back muscles. Your hands can help a little, just don’t press down too hard into the ball. This exercise is all about your posterior chain/your back side! Try to relax your glutes and breathe. After you complete your set, round yourself over the ball for a nice stretch of the spine.
