Start on your back with hands extended up over your head. Keeping your arms and legs as straight as possible, lift them up off the ground and towards each other. As you are lifting your arms and legs, slowly rotate toward one side so that one hand goes towards the opposite foot—if you can reach your foot touch it with your hand otherwise touch your shin or knee. At the top of the exercise your butt should be the only contact point with the ground. Slowly lower down until your hands and legs are 6-12 inches above the ground then repeat with a crossover to the other side.
