Stability Ball Ab Exercises: Oblique Curls

Video Transcript

"After you've mastered oblique work, that waistline lateral flexion that serves as the girdle of the spine on a mat, then we're going to try to work it in with the ball. Now obviously you've got to maintain control over this big cushion of air, hence the reasons why it's called stability ball. We're going to take one shoulder or chest -it all works as a unit- towards the opposite leg, but the crunch is really, the contraction's really coming from the same side of the waistline down into the leg, because that's the direction of the muscle fiber for obliques. So take a big inhale and exhale, and crunch, and release. Again, you're working lateral flexion. Instead of just straight up into the midsection we're working lateral flexion. Hand is just there for guidance. You should be able to see that elbow out to the side, but when it comes up, that elbow maintains the same position as it did when you started, and you're leading and crunching and holding, but not holding your breath, and release. Big inhale before you start and exhale. Work in about 10 reps on each side."
