Knuckle Up

Our whole family goes to this gym, the kids for BJJ and my husband and I for kickboxing. This gym is very much a community, all the coaches for BJJ are fantastic and work well with the kids while still having fun. The kickboxing and boxing coaches really give you a workout and know their stuff. We love this place!

Good gym, I'd definitely recommend it! This place has a great environment and trainers.also - the cancellation policy isn't as bad as other comments are making it seem. quite simple process for me

I have been training here in the Alpharetta location for just about a year now. I am SO FOREVER GRATEFUL that I chose to sign up at Knuckle Up right when I moved here from TX. The coaches and members here have changed my life. I'm not kidding! Each kickboxing class, I burn between 500-600 calories in an hour. In Muay Thai, I get to fine tune my technique and still burn between 400-500 calories in an hour. Yes, each one is killer workout, but it's SO MUCH FUN and MOTIVATION! The coaches are all professionals/fighters and GREAT teachers! Coach Mike and Stevie have no idea how much I appreciate their incredible classes! I highly recommend skipping the trial and just go straight to signing up! Okay okay fine - try it out for a week, but you won't regret it. Knuckle Up!

I love the KnuckleUp kickboxing classes! Although they can seem intimidating, the classes are actually very easy to get started with. The instructors do a great job of helping us newbies get in there and start getting fit. If you are truly wanting to lose weight and to keep it off, kickboxing is the way to go. Nobody does it better than KnuckleUp! I have tried some of their more popular competitors in the area. Nowhere have I had as much fun while getting in such a great workout than at KnuckleUp. I HIGHLY recommend them.

Been coming here for almost a year, and have had a great experience with the kid's program for Jiu Jitsu. The coaches are tough, but fair with the kid's, and the kids all get along with each other as a team! It is my son's only team sport right now, and he really clicks with kids boys and girls in same class... awesome. We initially didn't care about competition, just wanted the self confidence building. After 2 tournaments, my son has seen some success and it really reinforces his interest, and also helps with bonding even more. They start as early as 5 years old, and go through early teen years before transitioning to a adult program, which is fantastic... Alex, Marc, Pete, Brian, and Scott are all top-notch!

If you are serious about losing weight, building muscle and getting fit, then this gym is for you. I took a free Kickboxing class just to check it out and the next day I cancelled my membership at the Y and joined Knuckle Up Fitness. At first I did not like the idea of a contract, but the workout was so awesome and intense that I knew I wasnt throwing my money away. This is the best gym I have ever joined!

I think this is an ok gym and cancelled due to a work conflict. This is where my negative review starts. Good luck canceling! I have a month to month contract and cancelling is impossible. They force you to cancel via mail which they conveniently loose. I suspect they do it this way as there is no paper trail. It’s 2019, why can’t you cancel via email? I personally think there are better gyms around that offer cheaper membership, better class schedules and do not make cancelling impossible.

The managers were very courteous and helpful in leading me to class and making sure I got my phone charged. Clean and orderly workout area. The instructors were enjoying their occupational interactions. The BJJ class I took was fun and had a good mix of Players that enjoy the grind of BJJ. Members were polite and had gi’s that get washed regularly. Can’t wait to go back.
