Targets: rectus abdominus (“six-pack”)
Lie on the back and put the soles of your feet as close to your body as possible, with your knees bent out to sides. Put your hands behind your head, elbows in line with your ears. Keep the back flat on the floor and with the stomach muscles contracted, exhale and curl your chest up a few inches off the floor toward your legs. Lower to start. Repeat this 10 times.
