How to do it
- Lie on your side with your legs straight and stacked, and rest the hand of your lower arm on your abdomen. Place your upper hand behind your head with the elbow pointing up. This will be your starting position.
- Raise your torso and your legs toward each other at the same time, bringing your upper elbow toward your top hip and contracting the muscles down that side of your waist.
- Pause briefly at the top of the motion, then lower your torso and legs back to the starting position under control.
- Repeat for the desired amount of repetitions, then switch sides.
