Butt Kicks

1. Stand strong, with your feet placed at slightly narrower than shoulder width apart, a slight bend at the knee

2. Using your abdominal and calf muscles, begin to jog on the spot pulling your feet up to almost (for lack of a better term) ‘kick your own butt’ behind you

3. Maintain a loose body, always keeping a bend at the knee to cushion the impact

4. Continue for the specified amount of reps or time
