When you first start working out you should learn your BMI and your BMR. We'll help you figure out what those letters mean and how they can help you here!
Start at the top of a pushup position, hands gripping the edge of the platform, feet hip-width apart, with your body straight and parallel to the floor.
Jump feet forward to your hands, stand up straight and extend arms to lift BOSU over your head.
Reverse the move by squatting down and bringing the BOSU (dome-side) to the ground.
Jump feet out back to start position. This is one rep.
