If Yates walked into a gym and started showing people how to train, people would flock to him and work as hard as they could. Because they know he knows his shit, and they want results. He wouldn't have to ban people from walking out to get a water because they wouldn't be loitering around avoiding coming back to train with him.
Now, if you have to post up a rules board with 15-20 rules on it, it probably means nobody gives a shit enough to listen to you because they don't view you with reverence or respect enough to do so.
Ok, fair enough but I'm sure you realize we're talking about two different situations. I posted the rules I have for my teams and on campus facilities, not a commercial gym. I also posted this to give the thread starter an idea, because thats what he asked for, like I said, he could use it and modify it to his needs.
As far as my rules are concerned, most are for safety reasons but also discipline, most kids don't know their way around a weight room and as kids go, they need structure. Example, the ipod rule. If a kid is listening to an ipod with 40 other kids in the room and they cannot either hear me, their spotter or anyone else trying to gain their attention, it's a hazard but in a couple of the school weight rooms they have good sound systems, when they ask me if they can bring CD's the answer is always yes as long as it's not vulger, whatever it takes to motivate they're ass to train, they can bring it. The water and water bottle only rule is basically to keep the gym clean, spill anything other than water and it's a mess besides, water is the hydration liquid on the planet. You are right about one thing, it's hard to keep some kids motivated, it's not that they're not listening, most of the time it's because they are lazy, those are the one's that usually don't make the team and get cut. Varsity athletes are pretty easy to motivate because most want to win and they know that they are at that age, if talented enough could be on their way to a scholarship somewhere because they get looked at.
