Training is challenging but structured in a way that helps you build real skills while getting in shape. What I appreciate most is the culture -- everyone works hard, respects each other, and supports one another. It's not just about fighting; it's about discipline, growth, and learning every day. If you're serious about training MMA, jiu-jitsu, or striking, or just want to learn to defend yourself and become more confident this is the place to be.

Fantastic gym! Owner and Coach Ignacio is a Muaythai champion with lots of experience training…read morestudents. I've been coming here ever since they opened. KO1 Roundhouse uses a combination of Muay Thai techniques, cardio, circuit, weights, and strength training. You get a little bit of everything. The gym is setup where it's super convenient to drop in anytime you want during their opening hours. I love that I don't have a set time I need to be there because my work schedule fluctuates. Once you arrive, you start in the first round with jump rope to warm up. You then progress to some weights, and then get to box on the bags. Every day the workout changes so you aren't doing the same thing over and over. You get a personal trainer to guide you through each exercise and they will also hold pads for you for an extra workout. You can finish the training in 33 minutes or even stay longer. Their hours of operation are also really generous and I find I can always find a time slot within their opening hours to drop in. The facility is brand new and super clean. The staff cleans after each round so I feel I don't have to worry about someone else's sweat on the bags. The equipment is high quality and brand name. Cool gear too for purchase with shirts, sweatshirts, and boxing gloves. I'd highly recommend you give KO1 a try, they are great for all levels. New members can try a class for free before committing. Monthly membership fees are affordable and so worth it! P.S. They also do Muay Thai classes that you need to preschedule in advance but I haven't had time to check it out yet.

Old-school boxing gym…read more I read about this place in the 3/23/25 SF Chronicle newspaper and went to buy a t-shirt for a friend who is a long-time boxing aficionado. Located in a short cul de sac next to the frontage road just east of highway 880. Parking was haphazard. Was greeted by Celeste King, who owns and operates the gym now. Inside it's like a scene out of a boxing movie, old school and serious business. There's an elevated ring where two boxers were sparring, guys skipping rope, hitting the heavy & speed bags. Hundreds of posters and photos adorn the walls and ceilings, including ones that proclaim this the home of Andre Ward! I bought a t-shirt with their logo for a very reasonable $20. When my buddy visits me again I'll bring him here, he'll luv it no doubt.
