I've been having a problem lately at the gym that I wanted some input on. I'm a wrestling coach at the local high school, so I lift in the school weight room, but the football coach and myself have been butting heads lately. I think the room is usually to cold, so I shut the AC off and open the door to get some heat and fresh air in there, but the football coach says this is causing humidity to rust the bars and weight which I think is bull. So I was wondering what everyone thought a good temperature in the gym was? It's strictly free weights; no yoga or classes or anything like that. Thanks for any input.
