The lovely “Moose” will be demonstrating this exercise, start with two bosu balls one round side up and the other round side down. Position them so you can reach them with your feet on the one and forearms on the other.
Place your toes on the round side up bosu and forearms on the other. Maintain a perfect plank (an imaginary straight line between your shoulders, hips and heels). From the plank position go up onto one hand and then the other, now lower yourself back down to the starting position by reversing the order.
