Here's a couple....
1.
- Lie on your back, legs almost straight with your feet up on the ball (heels on ball, legs shoulder width apart).
- Arms can be out to your sides. As you get better, try doing it with them pointing to the ceiling.
- Raise your hips as high as you can, keeping your legs straight
- Keeping your hips high, bend your knees - rolling the ball towards you, and bringing your feet towards your ass.
- Hold the contraction for a second then, KEEPING YOUR HIPS HIGH, roll the ball away until your legs are almost straight.
- Lower your hips almost to the floor, then repeat.
You have to keep your hips high while rolling the ball, or this won't do much for you.
2.
- Set up similiarly to the first exercise, but just put one leg on the ball - hold the other leg up towards the ceiling.
- Now, lift your butt about a half inch off the floor.
- Using a vigorous thrusting motion, raise your hips as high as you can, without changing the angle of your knee.
- Hold at the top, then slowly lower.
- Repeat the thrusting motion, lowering slowly between each one.
