It’s a one-stop fight club at A4, which offers CrossFit, Muay Thai and MMA training in addition to the boxing classes. So if you like a little ass-kicking with your regular moves, this is the place for you. The classes are relatively small, which is good because there is probably a CrossFit class going on concurrently and it would suck to get an errant kettlebell in your face if it got crowded. That said, you get a pretty solid boxing workout, with each class focusing on a different skill (bag work, conditioning, etc.) depending on the day.
Pricing: $25 for one class, $129/month (+$79 initiation fee) for unlimited classes. First class is not free, but newbies can get a two-week trial for $20.
