Perform Move One on right leg and, without resting, continue to Move Two: From starting position, cross the extended right leg over the bent left leg, tap it on the floor, and return to the starting position. Do 20 taps; then do six push-ups (again, with leg extended and raised). Rest for 25 seconds with knees on the floor. Change legs and repeat Moves One and Two. (That's one set.) Do three sets, resting between them for 25 seconds with both knees on the floor.
