This inverted take on a total-body move will have you "heels over head."
  1. Start on all fours, feet close to a wall.
  2. Straighten your legs and raise your butt in the air, as you extend one leg toward the ceiling and place your toe on the wall.
  3. Raise the other leg and place your toe on the wall, so that you're in a modified handstand.
  4. Return both feet back to the floor one at a time, and repeat.
