Lie on your right side on an exercise mat. Use your right arm for stabilization, making sure you're not rolling forward and backward. Your legs are fully extended. Begin by bending your left knee and grasping your left foot and ankle with your left hand. Make sure your left thigh remains parallel to the right thigh - the left thigh doesn't drift forward and doesn't drift to the rear. Use your left hand to reach your left heel toward your left buttock, imagining you're reaching energy all the way down your left thigh. You'll feel a stretch down the front of your left thigh. Relax and return to the starting position.
