Lie on your back with your legs extended and your back straight. Keep your hips level and your lower back down on the floor.
Bend your right knee and hug your knee towards your chest, placing hands on your right leg.
Breathe deeply and hold for 10-30 seconds. Repeat on opposite side.
Stretch to the point of "mild discomfort," not to the point of pain. Never bounce. Try to keep your hips down and your shoulders relaxed.
