I'm going to be visiting New York (Manhattan) for a week and want to get training whilst I'm there. I'm a novice amateur with a few fights and am looking for some decent sparring. What gyms would you recommend I visit for price, quality and atmosphere? I'm also keen to visiting some gyms to watch some top-quality sparring. I've heard Gleason's is good for that. Are there any others you can recommend? Cheers.
