Cut a 6- to 8-foot length of cling wrap.
Fold the cling wrap twice vertically to form a long, flat band.
Hold one end of the band in your right hand. Lift your arm over your head and let the plastic hang over your back. Reach back and grab the plastic with your left hand. Pull the plastic wrap in either direction to stretch your arms. Switch hands and repeat.
Sit down on the floor with your legs extended. Pass the plastic wrap around the bottoms of your feet. Hold the plastic wrap in your hands at your sides. Sit back on your buttocks, bringing your legs in the air to form a "V" with your torso. Hold the plastic wrap at your sides for support. Tense your abdominal muscles and hold for one minute. Release and repeat.
Lie on your left side with your legs extended. Wrap the plastic wrap around your right foot. Hold the ends of the band in your right hand against your thigh. Raise the leg slowly, keeping the abdominal and gluteal muscles tense.
