Your arms are moving in this isometric exercise, but your core stays stable and still, making it a great isometric move. To make it even more difficult, Eric and Ryan recommended elevating your feet or using the ball to spell out your name!
- Begin in an elbow plank with your forearms resting on the top of a ball.
- Keeping your core strong and your body still, use your arms to roll the ball in a small clockwise circle. This completes one rep.
