Begin in a plank position with your shoulders over your wrists, your body in one straight line, and your feet together. Keep your belly button pulled into your spine.
Like the motion of a jumping jack, jump your legs and arms wide and complete a push-up, bending your elbows out to the sides and lowering your chest toward the ground.
With control, push your hands and toes into the ground, jumping back to the starting position with your feet close together and body in a straight line.
This counts as one rep. Repeat for 30 seconds.
This is an advanced move. If you need to modify it, do plank jacks instead, jumping your legs wide like a jumping jack without the push-up.
