Baboon jump

Ball your hands into fists and place your knuckles on the floor in front of your left foot. Keep them there as you jump to your left. Upon landing, lift your fists and swing them between your legs, shifting your weight to your left foot and straightening your right leg. Repeat in the other direction. Continue alternating.

Frog hop

Assume the starting position for the duck walk but place your weight on the balls of your feet instead of your heels. Maintain this position as you hop forward a few inches at a time. After 20 seconds, reverse direction, hopping backward. If this hurts your knees, perform another set of duck walks instead.
