Lie on your stomach on the floor, extend your arms out to your sides in a T position or slightly higher in a Y position and flex your feet, placing your toes on the floor.
Align your neck with your spine, bend your right knee and raise your right leg up so your right hip and quadriceps lift off the floor and your right butt cheek contracts.
Reach your right leg across your body, roll onto the side of your left hip, leg and foot, and place your right heel on the ground as close as you can to your left elbow. Rotate your lower back, but keep your torso and shoulders on the floor during the motion. Pause for two seconds in this position.
Reverse the motion and return your leg to the beginning position. Repeat the stretch with your other leg, and continue alternating your legs until you complete five to 10 repetitions on each side.
