The Swiss Ball Rollout is a core exercise that primarily targets the abdominal muscles, but also works the obliques. This is a core exercise which is well suited to advanced lifters.
- Get into a plank position with your elbows resting on a swiss ball and your feet firmly planted on the floor.
- Keeping your back straight, glutes tensed and core tight, roll the ball forwards by extending your arms.
- Roll the ball backwards again by bending your arms to return to the starting position.
