From the reviews
KnuckleUp has been one of the best decisions we’ve made for our son. Austen runs an excellent program for both kids and adults, and his ability to coach across different age groups really shows his passion and dedication to the sport. I’ve seen other coaches, but his training style truly stands out.
Knuckleup is where it’s at! Was pretty consistent for a few years before I had to relocate. Came back after almost 4 years and it was like riding a bike. Coach Austin was just as welcoming and patient and enthusiastic as ever! Lots of new faces to me but the old camaraderie was still there!
This program is fantastic. My son and his friends have been enrolled for a few months, and he really enjoys it. I recommend it to any parent searching for a self-defense course. They also offer classes for adults, which I’ve been considering myself.
This gym offers top tier training, great energy & motivating coaches. The environment is welcoming but intense to challenge you every session. If your serious about your fitness journey, wanting to learn jiu jitsu, striking or improve conditioning, this is the place to be!
New to muay thai? Start at KnuckleUp Academy
KnuckleUp Academy comes up as a beginner-friendly gym — noted on their own site. 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 Academy
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.
