you know this already but location is important,if you open it to close to another already established hardcore gym it could be rough for ya,alot of guys wont just leave thier gym to go to another one.believe it or not hardcore gyms seem to doo better in the urban areas compared to the suburban areas cause alot of these dudes arent looking to get tied into long term cintracts but rather pay as you go type of deals,im not sure about the price to be honest as far as opening a gym but id get plenty of free weights as well as dumbells and throw in some nice hammer strength pieces and stuff,im sure you got that part figured out since you workout and know what the members like and what they dont like,good luck to ya if you do and i hope it works out,im sure youll enjoy it cause you like the bodybuilding scene and your not just in it for the profit
