I recognize professional boxers have come here to train. But I think the golden days of this gym are far gone.
From what I saw, this is a great place if you're a girl. Coach will definitely watch your every single move and teach you 1 on 1. If you're a guy, you'll be told to hit the bag in the far corner. You probably will be developing the wrong form for days/weeks/months. I've got a bag at home; I came to the gym to learn technique, which I didn't learn any. Furthermore the conditioning is not structured very well (no timing, doesn't work out full body, etc).
The technical coach (Winslow) is a far better coach, and shows great professionalism, but he's usually busy with experienced fighters.
FYI: I didn't use a groupon; I paid full hoping to get coaching.
