Lie flat on your back, grab the sides of the ball with your feet while the ball is on the floor. With the ball between your feet, raise your feet and arms up toward the ceiling. Exchange the ball to your hands and lower both legs and hands to the ground. Repeat, alternating the ball between your feet and hands.
Do this exercise with the best exercise equipment. We recommend using a bluetooth chest strap heart rate monitor or a smartwatch for more training optimization & performance tracking.
