Begin by laying on your back. Keep your back flat on the mat, pressing your pelvis into the mat.

Lift your legs off of the ground, straight out in front of you.

Place your hands lightly behind your head, opening your chest and elbows up and out.

Alternate bringing your right elbow to your left knee and left elbow to right knee. Be sure to keep a slight bend in your knees at all time. You want to feel the workout in your abdominals. If you are feeling it in your hips, raise your legs higher to isolate your abs.
