The Rollout exercise works your arms, abs and back.
This is the Swiss ball rollout. It's a very good core exercise. You're gonna be on both knees, very tall posture. Your hands are gonna be interlaced and placed on top of the ball with the arms straight. The movement is gonna be as one as the hips and the shoulders and the body are gonna come forward as the arms roll across the top of the ball. Good. Come back. So what you're gonna do is you're going to take 2 seconds to roll out and 1 second to return. You're gonna keep your abs tight and a nice little arch in the lower back. What you don't want is any collapsing of the hips towards the floor or rounding of the lower back. One more rep. Perfect.
