I'm going to check out a boxing gym today but want to get some info so I can be prepared and no what to expect. I've got a background in Tae Kwon do, and have done muay thai and bjj on and off. This is my first time going to a boxing gym. It sounds like there's no actual class schedule and you just come in while the gym is open. I'm thinking you would probably just hit the bags and spar and occasionally pay for private instruction to correct mistakes. Is that how things go in most boxing gyms?
