My girlfriend and I were having a discussion the other day about the use of stability balls for exercise (specifically the use of balls with the average personal training client).
I took the stance that they are pretty much useless as an exercise tool for lifters (especially novices). Of course, this lead me to wondering if there is, in fact, a time and place where stability balls are of value. If memory serves correctly I remember a picture of John Davies squatting on a ball.
My question has two parts:
Do you believe that stability balls offer any benefit to a trainee? If so, what are they?
When (if ever) is the use of the ball warranted.
