Lie face down on mat and hold arms out to sides at shoulder-height, thumbs facing up. Lift chest, arms and legs off ground simultaneously. Pause, then lower back to mat. Do 10 reps, then rest for 30 seconds.
Lay on the floor on your stomach. Lift your body off the ground, supporting your upper body with your elbows directly under your shoulders and your forearms flat on the ground. Keep your body in a straight line from your shoulders to your heels and hold for 30 seconds. Work up to holding for 60 seconds or longer.
Lie face-down on the ball, and walk your body forward so it supports your hips only, hands on the floor. Squeeze your glutes and raise your legs behind you until they’re level with your torso.
