GREAT Article! Thanks for the link!
I especially liked: "Call me crazy, but having a client perform a one-legged squat on a foam pad while holding a medicine ball above their head is NOT functional. It’s a waste of time. The same can be said for squatting on BOSU balls."
I always wondered if the trainers at my fitness center knew something I did not, with teaching all their clients to do all that balance stuff and machines and never teach anybody to squat or deadlift with free weights!
