Lie on your left side with a physioball supporting your lower hip. Place your feet where the wall meets the floor for stability. Your legs should be spread about 3 feet apart with the toes of both feet pointing straight ahead. Lift your right arm straight up so your fingertips point toward the ceiling, and place the palm of your left hand against your sternum. Tighten your core and slowly lower your torso to the left side. Engage your right obliques to lift yourself back up. Repeat all reps on your left, then switch sides.
Reps: 10 on each side
