"The more movement we create with a stability ball, the more leverage and momentum we have to control. Once you've mastered having it close to your body, and you've been sitting on top of it and you've got that mastered; now we're going to start using it to control momentum. We're going to put it between our feet like this. Start with your head flat and we're going to do a reverse curl. Come up. Try and keep your feet in line with your knees and your hips, and then you come out 45 preferably. If you can go lower and still keep that back anchored to the mat, that's good. But once you feel the back come off the mat, exercise is over. Come back up. Hold it. Reach up towards the ceiling and control back down either 45 or 90. Come up. Hold it. Everything is smooth and controlled. And up, hold it, and you're getting work the entire way up, and the entire way down. Make sure you get a good stretch, and incorporate your low back as well."
