I get annoyed by one bird at the gym who sticks her elbows out when using the punching bag and she bobs up and down like she's doing breaststroke. I'm surprised the trainers don't pull her up on it to be honest, they certainly wouldn't let me get away with it. I guess it's good that I'm being taught the right way and it's her loss, still annoys the * out of me to look at her.
