This is step 2.
Step 1: Lay on your back. Bend your knees and touch the bottoms of your feet together making a diamond shape and resting your legs on the floor.
Step 2: Place your hands behind your head and curl your head and knees up and toward each other, keeping the diamond shape with your legs. Squeeze your tummy muscles as you go.
Step 3: Return to the original position.
I really like this ab exercise because it works the upper and lower abdominals. I try to hit 50 reps. My baby ravaged belly needs it.
