Can I run a "potentially dangerous" business without being sued?

I had an idea to open a place where people can come to take out stress by going into a room with a cut-resistant jumpsuit, face mask, gloves, etc on and smashing various glass, or “smashable” items with a bat. (Or something like that). I can only imagine the legal issues with a business like that. But is it possible to have a form of waiver that says something along the lines of: Enter at your own risk (with more complicated legal words)? I would obviously make every effort possible to avoid injury. Where can I find out more info about this?
