1. Squat down with your feet straight forward, your heels on the ground and your knees tracking over your toes.
2. Jump back to a plank position, and land with your abs braced and without arching your back.
3. Keep your ribs down and your tailbone tucked under while in the plank position to keep your lower back from arching.
4. Jump back to the squat position with your heels on the ground, knees straight forward and feet straight.
5. Jump upward and drop down to repeat.
