First important comment before going through the logos is to please do not use our own slogan, expecially that one "Fun & Sweat" as we do need your own ideas and suggestions. As i said it's a boxing gym so you can start from the main point: why kids and teens as well as women and men would join this kind of club. The reasons could be: fitness, losing weight, self defence, becoming an amator then, maybe, a professional boxer, having fun, getting in shape, stamina etc.
