I suppose that any martial art school (especially a kickboxing or boxing club) that spars could be considered a "fight club". If you want to have a "fight club" I suggest, -Get a private room. -Make sure you have insurance -Sign some kind of wavier -No exchange of money for the sparring matches -Proper protection equipment. (Cup, mouth piece, gloves, and some type of amature head gear) -Invite only people who are not "hot heads" Or you could join a martial art school that spars the way you want OR have your instructor have sparring nights where guys can do this type of things.
