Obliques Crunch
Target Muscles: obliques, rectus abdominis
Set Up: Begin by lying faceup on a mat. Place your hands lightly behind your head and lift your legs, with your knees bent to 90 degrees and calves parallel to the floor as shown. (Beginners: Leave your feet on the ground.)
Action: Contract your abs and lift your shoulders from the mat. As you rise, rotate through your waist to direct your right elbow towards your left knee; immediately turn to the right, directing your left elbow towards your right knee, to complete one rep. Return to the start.
