I'm all for core training, but those swiss balls seem really gimmicky. Having to keep yourself balanced, even when weighted, doesn't seem like it can cause sufficient microtrauma to promote muscle growth.
Then again, my litmus test is that if the hack trainers at my Gold's are promoting it, it's gotta be worthless.
