Earlier this year I started a new job at a gym.
1st thing I saw was one of our female trainers standing on a swiss ball doing squats. She had just learned to do it and was so happy because it was a "true test of fitness" according to her.
She started teaching all her clients to do it and recommended all our other PT's to do them, made them a big focus of one her classes as well.
Last week she fell off one of the balls doing squats and broke her wrist, needing surgery and 3 pins and some rods put in.
She vows not to stop swiss ball squatting.
Anyone else got any stupid PT tricks?
