15-Minute Crunch-Free Ab Workout
Sit on a bench or chair and place both hands on your abdomen. Inhale and expand your belly, feeling your hands move out. Exhale and contract your abdominals—imagine pulling them in all the way to your spine. Maintain the contraction for 30 counts (to make sure you don’t hold your breath, count out loud). Then do 10 small squeezes.
