1. Place your stomach and chest on the ball reaching your arms to the floor. Slowly walk your upper body forward until your thighs are resting on top of the ball. Squeeze your abs tight to hold this plank position and do not arch your back.
2. Keep your abs tight to balance. With your arms opened wide and hands on the floor, slowly lower down to the floor and push back up to a plank position.
3. Squeeze your stomach in tight and pull your knees towards your chest as far as you can, rolling the ball towards your arms, creating a tuck position. Slowly roll the ball back out, straightening your legs back to a plank position.
