Ball Exercises for the Abs and Butt
Kneeling Ball Rotation
This is a great, combined stretch and strengthening exercise for the lateral abdominal muscles.
Start by kneeling in front of the ball, keep your back straight, and place your hands on the ball.
Proceed to roll the ball forward, holding it from the sides. Stretch the trunk, keeping it parallel to the ground. Maintain the abdominal muscles contracted.
Proceed to rotate the ball by twisting your trunk to the side, keeping your knees on the ground. Hold for 3 seconds and resume starting position. Switch to the other side. Repeat 5-10 times each side.
