This circling plank is an anterior core stability exercise that teaches you to prevent excessive spine extension known as arching your spine. This move is great for intermediate and advanced levels.
- 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.
