Stand on a hardwood or linoleum floor with socks on (remove shoes for this move). Lift left heel, and slowly slide leg back and to side at a 45-degree angle, bending right leg. (Lower as far as you can comfortably.) Keep chest lifted, and don’t allow right knee to move past toes. Hold for a count of three, then squeeze buttocks as you slide leg back to start position. Perform 8 to 12 repetitions, then switch legs. To increase difficulty: Lift foot off floor after you extend it, then place it back to return to start position.
