Based on the positive Yelp reviews, I randomly picked One Martial Arts to start kickboxing while I was going through a divorce. I had no idea it was going to ruin me for future fitness classes! I moved to the East Bay last year, and there is nothing--NOTHING--similar to the amazing kickboxing classes at One Martial Arts. I miss TJ's class so much I have literally cried. It is so fun, TJ is incredibly motivating, the music is energetic, there is no huge learning curve to punching and kicking the bag like in a formal martial arts class, and I never once got bloody knuckles from punching because their bags are so much more pliable than a heavyweight bag (East Bay folks seem to enjoy punching and kicking blocks of concrete). I would give One Martial Arts 20 stars if I could. At some point in my desperate East Bay search I'm sure I will go back to spending the 2-3 hours in traffic to work out there again.

So intense but super fun and engaging. Nonstop action but go at your own pace. They don't spend an eternity on warm up and running around which allows more time to spend w/ your own bag. TJ is incredibly nice. Came to check on me a few times but didn't chat too long so that I can focus on my freestyle. Clean mats and dojo, overall. Great workout...more so than BAFA in Hayward and a lot closer, too.

I was fortunate enough to have a few months off work. During which time, I started attending the weekday kickboxing classes at OMA to try something different. There isn't a lot of fitness options here in the Outer Sunset, and I needed something more than running.

I was hooked after my first class. I love that the class is intense, but you can still go at your own pace. After a few classes, I noticed the difference in my overall fit.

Two weeks later, I dragged my husband to join me in a Sunday class, and now he loves it, too.

All of their instructors are great! I've had Jason, Dexter, Gail, TJ and Lucas. Each have their own style but are consistent in that they really motivate you.

I stumbled upon One Martial Arts on a great groupon deal and 1 yr later I am still going strong! Their kickboxing classes are great for people of all fitness levels from your typical couch potato (this was me), to the relatively fit, to the actively fit. The instructors are all very nice and wonderful motivators. They will push you to work your hardest and go beyond your comfort zone. OMA kickboxing has enabled me to enjoy working out regularly because of this, I am now healthiest version of me (cheesy, I know). I am so grateful to have found this place!

I've been coming here regularly for about a year and half now. The kickboxing class here is a fantastic cardio workout for anyone who sits in front of a computer everyday! The location is superb if you live near sunset and work in downtown. The group instructors and staffs are really nice and helpful as well. Kickboxing is my favorite workout. I've got to punch and kick and running around. It's super flexible. You can practice combos and techniques but you can also choose to focus on building strength or agility. You can come to a session even if you are very tired after a long working day and still enjoyed a very good workout under the music and instructions. You can go as slow as you want or make it as intense as you'd like it to be but as long as you keep coming at a regular basis you will benefit a lot. Enrolling in a monthly program really helped me keep coming to class and gradually developed a workout routine that involves kickboxing, jogging and more. It definitely made me more energetic at work. I've been able to start living a much healthier life style ever since and keep getting closer to my fitness goals. Special thanks to all the instructors and Caryn!

I love this place. The kickboxing instructors are knowledgeable and supportive, knowing just how to push you without making you uncomfortable or unsafe. They're kind and funny and stellar all around. The classes are a good mix of ages and fitness levels.

Love this place! I went from working out maybe 5 times in a year at the regular gym to being so dedicated to this kickboxing class that I usually go 3x/week. Professor and the entire team is so inspiring and motivational. Also love that I can bring my kids with me so nothing holds me back from investing in my own health. Highly recommend.
