Squats on physioball

Caution; this is an advanced exercise. As with all balance exercises there is a slippery slope between the benefits and risks of an exercise. Although this exercise is extremely effective for all of the stabilizer muscles used in a squat is it dangerous, please use extreme caution. When adding more weight doesn't seem to be having much impact to your gains, you can always decrease stability for a more difficult workout.
Getting started.
*Be sure you are competent in free/body weight squatting. Practice on the BOSU and one leg.
*Getting on and off the ball is probably the most dangerous, have a spotter or be next to something you can hang onto.
*Make sure you are centered.
*Dismount before you are exhausted and fall.

This exercise is great for all sports that require balance and abductor, adductor strength, in particular skiing, horse back riding, and basketball.
