il admit iv interupted people to correct their form, whether i was a dick or not i dont care i jsut could sit back and watch someone give themselves a nasty injury. Iv seen people do in their back deadlifting, pop their shoulders out doing too heavy bad form presses scrweed up knees from bad stupidly heavy squats.
I dont go around telling people how to correct obvious inbalances or workouts that will lead to them, might mention it to the on duty instructor or something but yeh my advice usualy is only the form of 'o shit he might hurt himself this rep let alone injuries down the line etc' as ambulance usualy = gym shut down for a bit or that area of it.
i mean if people are working out so much that they get the classic turtle back from only doing chest and bicepts....i lol at them for trying to be cool and failing!
O i also hate gyms that dont kick out or temp ban the clearly anorexic teen girls who come in and jsut go on a cardio machine for 2 hours looks like skeletor on a come down....they need to be stopped for their own good and the under 18 ones need to have their parents contacted to get them help!
