- From a standing position, squat down and place your palms on the floor in front of you, shoulder-width apart.
- Jump (or step if you’re just learning) your feet backward so that you’re in a plank position (arms straight, legs fully extended). Keep your abs braced, and don’t let your back sway.
- Jump your feet forward again and stand up. Repeat the exercise.
- As you improve, add a pushup before you jump your feet forward; then as you stand up, jump straight up in the air as high as you can before dropping back into the squat position.
Form tip: Your motion should be fluid throughout the exercise.
