Perform Moves One, Two, and Three on the right leg; then, without resting, add Move Four: Bring the right knee in toward the chest and then rotate it outward, like a dog lifting its leg. Bring the knee down, and move the leg back to starting position. Repeat 20 times. (The movement comes from your hip, and the knee shouldn't be lifted higher than your waist.) Next do six push-ups with leg raised as before. Rest for 15 seconds before repeating Moves One through Four with the other leg.
