I'm going to say this without hyperbole: This gym and the people in it have changed my life. My…read morebody and mind have gone through dramatic shifts in just over 3 months; from the darkest depths of depression, self-doubt, weakness, and laziness, to camaraderie, purpose, strength, and positivity. This is the type of gym you come to to learn and work at. The mirrors here are for technique, not flexing. The ring is for work, not Instagram. You don't want to waste a single minute of your time here, because any time this gym offers you is limited time that you need to value. And if you don't, you're stealing from the next person in line who cares more than you do. There is an air of machismo that permeates the space, but that doesn't imply sexism - it's something different. It's something that anyone of any gender can appreciate and use as a tool to advance their craft. It's something hard, smart, vicious - it feels revived and repurposed from days past, and it's something you may not even know you need. I did. And if you're reading this, you might too. Try to get a spot here. Sign up for just one class. It's not going to be for everyone, but you'll know right away if it's for you. And if it is, you're going to find exactly what you needed. Thank God this spot is here. I don't know what I'd do without it.

A great place to learn Boxing without breaking the bank. The setup is very much like a college gym…read morethat is: the workout of the day is written on the board, you do it to the best of your ability followed by bag work, pad work and coaching advice on your boxing technique. Overall I think that this gym offers a great Bang For The Buck considering that most Manhattan style Boxing gym's Segment and Monetize individual activities such as one on one coaching, pad-work or even the opportunity to spar. This gym, however, does it more or less as a complete package and at a reasonable rate. Including, if you can make it, Boxing/Boot Camp style classes in the morning, instructed by the owner. Like most boxing gyms in NYC, this GYM is somewhat rough around the edges. But when you get to know the people that work here and the trainers you will soon see you made a good discussion joining this gym, if your intentions are to get in shape and learn the art of pugilism. In a Nutshell, ... A TOTAL PACKAGE ....it's a good place to learn the sweet science without burning a big hole in your wallet.

If I did not choose this gym, I don't think I would have stuck through with my fitness journey…read more Point-blank and simple. When I first wanted to start working out, I was fairly uncomfortable with the idea of being in a huge gym and having to work out in front of people. I looked for a long time to find a space that was close to me that offered privacy. Sevenbell was one of those gyms, and while it was a little inconvenient to get to from my location, I decided to give it a try. I believe it was one of the best decisions I made. The gym is always spotless, never crowded, and I always felt comfortable in the space. When I went here (I no longer live in the area and have since changed gyms) I actually looked forward to coming every day, because I knew I would not have to sit around and wait for a machine to be free, or have to deal with rude people making noise and slamming weights. If you are like me and are looking for a gym that is clean, quiet, and accepting of everyone no matter where they are on their fitness journey, then this is the place for you. It is well worth the price and I could not be happier with the time I had spent there. Also, the personal trainers are amazing. I worked with Jesse while I was there, and I felt he did a great job with giving me a foundation to work with in my personal workouts. Cam (who is like 6'5 and looks like The Hulk after he transforms) walked by me one day and mentioned that I looked bigger, and that my form was good. It felt like I won the lottery :)

I…read moreoriginally reached out to lose weight and get healthy, but I have felt challenged and encouraged to do more. Gashford's training sessions mix Muay Thai and regular weight lifting with some cardio. In only a couple months, I feel much stronger and have noticed increased focus and energy during the day after each session. He also has helped with meal planning and explains the science behind his workouts which i really appreciate. I've never really seen more than 10-15 people in the facility at a time, and as someone who hates big gyms, it's a super welcoming environments for complete newbies like myself. Perfect place and trainer if you're looking to mix up your workouts and create a real life style change!

I went to Gleasons since I needed some bag work since I just got to New York. Coming in front desk personal will help you with your needs and charge you for your drop in and from there really you're ready to go. It's fairly an old school boxing gym and has a lot of culture. There was times when I would just mire the pictures all over the gym and really look at the history of how boxing came to be. I was offered to get some mitt work from one of the trainers but respectfully declined and was thankful though because some gyms just let you come in and out which is the goal overall. The gym was pretty busy at the time as well because the nearby hs youth came by for a fundraiser and there was free food and just prizes being given to the youth which was nice to see. I was also able to train near Pro boxers that were being filmed by either Top Rank/Dazn and it was amazing! I really was fanboying it out since I was training there and being surrounded by so much! All in all I'd recommend this gym to those who are either starting out in boxing and need a boxing home base near the Brooklyn area but also very friendly to those who just are in town and need a good sweat in or even just learn boxing basics!

There is no better gym in New York…read more Here you can not only find some of the most talented fighters in New York, but also friendly folks (both members and trainers assistants) who make it their goal to work with you to make you the best you can be. This gym also has a reputation for helping folks cut weight. I know many members who have lost 30 - 80 (yes, 80!) lbs here! I myself saw a max loss of 28 lbs. (202 down to 174 at one point.) Greg Ardon, the unassuming owner of this gym (known for his training of Hilary Swank in Million Dollar Baby), has a patient, quiet style that is combined with his extreme knowledge of fighting and a slick sense of humor. With that being said, the biggest lessons you learn here are modesty, self-confidence, and courtesy. These three things are more important than any bag you can hit, weight you can lift, or rope you can skip. I highly recommend you try this gym. 2011 Update: This gym is now officially a pro gym. That means they can train pro fighters, represent pro fighters, and their fighters can compete on a professional level, as well.

In this place I found that true self confidence comes from within and has little to do with the materials you own, the clothes you wear, or the money you make. I was in a bad place when I decided to try boxing. But I knew I was angry and wanted to punch something, so boxing was the light bulb that went off in my head. I did a lot of research trying to find a good gym. I read the whole website and was absorbed in the stories. Immediately inspired I booked it to the subway station. 45 minutes later I almost got cold feet on the 1 train thinking I couldn't walk into a boxing gym, I just thought I didn't belong. The lady at the front desk helped wash away my fears. She was so welcoming and genuine I became a little more comfortable. I signed up and continued to go (nearly weekly) until I left New York. All of the trainers are knowledgeable and good people. But no one tested me as much as Eric Kelly did. He had a nickname for me, 13, because apparently that's how old I look. He was brash, no nonsense, demanding your best only and always. It was exactly what I needed, I improved, I became strong, and most importantly I saw my limits and pushed past them, which was so rewarding. I faced my fears every time I walked into that gym and I felt invincible every time I left. Intensive. Life Changing. Shout out to Eric: thanks for everything.
