Martial Arts Schools in Boston

“I’ve been coming to this gym for about a year now, and it has completely transformed how I feel about fitness. Grayson has been my main personal trainer, and he’s genuinely exceptional — consistently prepared, incredibly knowledgeable, and always able to strike that perfect balance between pushing me and supporting me. He pays attention to the details, adjusts sessions based on how I’m feeling that day, and explains the “why” behind every movement. Training with him has made me stronger, more confident, and way more consistent with my routine than I ever thought I’d be.

I’ve also had a few sessions with Chi and Aidan, and each of them brings something unique to the table. Chi, who’s also the owner, deserves a special mention. He’s incredibly kind, patient, and genuinely cares about every person who walks in. You can feel that the community and atmosphere here come directly from his leadership and personality.

The gym is clean, welcoming, and never overcrowded. Workouts are tailored, effective, and actually enjoyable. After a year here, I genuinely look forward to training and feel better than ever.

Couldn’t recommend this place more — if you’re looking for real personal training with trainers who truly care, this is the spot“

“Amazing institute. It is an honor for my family to be trained by Master Kim and his team. Values such discipline, precision and strength are instilled every lesson. Location is also very convenient.“

“I’ve been attending the adult strength & conditioning classes with Master Gomes for years, and they’ve been nothing short of transformative. Master Gomes is an exceptional motivator who knows exactly how to bring out the best in each participant. His ability to recognize individual strengths and weaknesses, ensures everyone gets personalized attention. He’s a highly knowledgeable coach and strength trainer and places strong emphasis on injury prevention, which gave me confidence to push myself safely. The classes are fun, engaging, and highly effective—I’ve felt my strength & agility improve significantly. Highly recommend to anyone looking to work out in a supportive, dynamic environment. As a side note, I’m feeling stronger than my identical twin - who agrees (and who’s currently sidelined with an injury from working out at a different facility)!“

“Mr. Davis is an Amazing & deeply knowledgeable individual. His teachings give you a full rounded picture of the progression of Japanese martial arts & applicable tools for modern day situations.“

“So happy we found One Step Beyond! My boys (6 and 9) tried soccer, baseball, flag football, but nothing “stuck” until we discovered karate back in March 2021. Fast forward to two classes a week (soon to be 4 ?), 2 belt tests and now a competition team/weapons (all dull, nothing sharp here), my boys couldn’t be happier. Sensei Marie and Sensei Erin are wonderful with the kids and it’s a wide range of all ages and backgrounds. I can honestly say that karate has also taught my boys discipline, fitness, patience and self esteem. I highly recommend One Step Beyond!“

“Come join the best martial arts class in town. Helping to build confidence in our youth to help them become who they strive to be. The best instructors around and Kyoshi is one of a kind. I wish I could tell you more but I don’t want to spoil all the fun. Come down and check it out for yourself. Just a trial run will have you joining and that I stand firm on.“
