Lemon Squeezer
1. Lie supine on the floor. Lift your legs, head, neck, and shoulders slightly off the floor, being careful not to arch your lower back. Your arms should be raised and parallel to the floor.
2. Pulling your knees in towards your chest, reach your arms forwards to your ankles, so that your torso lifts completely off the floor.
3. Slowly open up, lengthening your legs and lower your torso back to the starting position.
4. Repeat the motion without completely lying down on the mat. Repeat fifteen times for two sets.
