Basic Crunches For Abs!

Doing yoga on the ball can benefit anyone, including strong, limber athletes. Raise the bar on your yoga workout by adding ball work. Poses done on the round surface challenge balance and build core muscles while helping you develop inner focus.
Basic Crunches for Abs
With your feet flat on the floor, place your lower back on the ball, and your upper body and thighs parallel to the floor. Do crunches as usual, lifting only your shoulders and upper back off the ball, using your abs.
In normal everyday activity and traditional exercise, larger muscles tend to do most of the work, so the small ones weaken from lack of use, she explains. However, when you do yoga movements on the unstable surface of a ball, you strengthen those tiny, overlooked muscles through the micro-movements you make to stabilize yourself. Just sitting on the ball at your desk engages those smaller muscles effectively!
Caring For your Balance Ball
Before use, check the area for sharp objects that may puncture the ball. If possible, use a carpeted surface or exercise mat when using the ball. The ball is not intended for outdoor use as the risk of puncture is high. The ball should be inspected for gouges and deep scratches prior to use.
Getting the Right Fitness Ball
Fitness balls come in different sizes. The basic rule for choosing the correct size is that when you're sitting on the ball, you should be able to easily balance with your feet on the ground. Your hips and knees should both be at right angles. The following list matches you up with the right size ball, based on your height:
This is a simple, cheap way to get a little more use out of your exercise ball. The ability to add resistance bands (without safety being an issue) adds a whole new dynamic to how you use your exercise ball.
