So what are you basically "allowed" to do?
LOL, i was wondering it myself. Sit on a bench and be quiet, but don't sit there too long.
Kidding aside, this is typical for Japan. You put up a shitload of rules, and everybody follows them to a point where it becomes ridiculous. For example, there's this HUGE MMA-Fighter who trains in the gym, he has lots and lots of tattoos. Now according to the rules you cannot make a contract when you have tattoos, and when you get some after you made the contract, you can be suspended from the gym.
But, he dwarfs the trainers and almost everyone, so nobody says anything.
Some competitors also do supersets, or forced reps. They know what they are doing, so nobody says anything.
All in all, it is the cleanest, best gym i have ever been to. No phones, no assholes, no hardcore attitude. It's good to have rules when you can bend them a tad without getting problems.
