From the reviews
Amazing gym with a great staff, class schedule, and culture. They were very transparent about fees and the cancellation policy when I initially registered and have always been available for questions about my membership. Highly recommend giving this gym a chance, especially since they offer a free trial.
Very friendly staff. Great coaches. I mostly do CrossFit and boxing. Have tried kickboxing couple times. The instructors are great and the members are supportive and helpful. I joined a month after moving to the area from NYC and I’m glad I did.
This school (and I've been to a few) is great! So much so that my son joined too. The owner and instructors really stress the practicality of techniques for the beginners and the safe practice for all students.
KnuckleUp has been eye opening! I came into the gym with a very surface level knowledge of combat sports (loved watching mma, and was always into some of the components of it), and I feel like I learn every time I’m here. Their group classes are awesome, with high energy and friendly instructors.
New to muay thai? Start at KnuckleUp Fitness
KnuckleUp Fitness comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never thrown a punch or a kick, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first muay thai class at KnuckleUp Fitness
Nervous about walking into a muay thai gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.
