From the reviews
Extreme Power Gym is exactly that, extreme with focus on power of the mind, body and spirit. Not only is Ajahn Ruben Rowell the highest level master teacher, he is also a mentor and someone who cares deeply about his students.
Great gym with an amazing community. My daughter has been going here for 3 years now. She started in the kids class in 5th grade and recently moved into the teen/adult classes as she’s starting high school. Ajahn has been such a positive influence in her life.
Coming to Extreme power gym has been such a fulfilling experience. I moved to the area recently and was hopeful to find a good gym, what I found at Extreme Power is a not just a gym but a school, a teacher of true Muay Thai, a community of students who are welcoming and kind and present as true martial artist.
I brought my son here when he was turning age 4 after searching different places. My son has a brain disorder, but Muay Thai really helped enhance that. EPG helped with his confidence, with him being sure of his self when the bullies persist.
New to muay thai? Start at Extreme Power Gym
Extreme Power Gym 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 Extreme Power Gym
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.
