For the Back
(A) Lie on your back with your knees bent and feet on the floor. Curl your hands into fists and extend your arms upward.
(B) Tighten your abs and lift your legs so that your knees are over your hips and bent at a 90-degree angle.
(C) Keeping your core engaged, lower your right heel to the floor as you bring your right fist to your left knee. Return to the starting position; switch sides. This is one repetition. Repeat 20 times.
