Place the back of the chair against the wall. Sit with your right side facing the wall and pull in your abs, holding the back of the chair with your left hand. Turn and place your right palm on the wall at an angle behind you with your arm straight; keep your gaze straight ahead.
Hold for 30 seconds, keeping your abs tight and breathing gently, then switch sides.
