It's not just for fighters--it's an incredible place for hobbyists, beginners, and anyone looking to get in shape. At the same time, some of the Bay Area's top fighters train here. I was one of California's highest-ranked amateur MMA fighters, and today I'm one of the state's top professional fighters--even though I only compete once a year! Come check out Bay Area Fight Academy. Everyone is welcome!

I went in to check out the gym after the head coach told me I could come by anytime, and I was…read morealready pretty nervous since I'm new to MMA. Unfortunately, one of the staff members -- a heavier-set guy with glasses -- came across as rude and dismissive toward me, which made the experience uncomfortable. As a beginner, first impressions matter a lot, and instead of feeling welcomed I felt talked down to. The head coach himself seemed respectful, which is why I'm leaving this review honestly instead of just writing the whole gym off. I just think new people should be treated with more patience and respect, especially when they're stepping out of their comfort zone to try something new.

The training/workouts 10/10. Information and Knowledge 10/10. Cancellation process -100/10…read more Seriously, the most painstakingly frustrating and tedious process I've EVER experienced at any business, ever, period. Felt a bit misguided because of course signup process was as easy as 123, but in order to cancel my membership (which I had to do for personal reasons) I had to write a letter, get it NOTARIZED (yes seriously) , and drop off in person, AND $100 cancellation fee lol. Guess there's a catch to finding the most affordable muy Thai in the Bay Area. In all honesty it did feel like communication was solid up until I started inquiring about cancelling. As soon as I started inquiring bout cancelling it felt like I could not receive a response. Had to message repeatedly, and felt like my calls were being dodged intentionally. I would call from my phone and calls went to voicemail repeatedly. Tried using my friends phone to call and they answered on first call lol. Just didn't feel very professional or helpful. Finally got my membership cancelled though after much effort and communication. All in all, this is a great place for muy Thai, and the coaches have extensive knowledge of what they're doing and create a welcome environment for new students. Like my review states, My critiques lie solely with the dated, frustrating, tedious cancellation policy. Come for the good vibes and solid training, and stay because you probably won't have a choice, bc you won't be able to cancel LOL.

The trainer let me in, instructed me where to put my stuff, had me fill out some forms, and gave an overview of what to expect. I honestly did not know what to expect when I first arrived, but I was not expected to jump into the workout immediately. He explained what to expect in less than three minutes. I was given maybe less than a minute to stretch and get ready before my first round was up. It was nice to be able to see the workout on the screen and get some help from the trainer when needed. The staff was really nice and gave me tips when I hit the kickboxing rounds. I learned that you could drop in whenever you wanted, and there weren't structured times or appointments required since all of the workouts were on the screens. I found that I enjoy workout classes that have an actual instructor more so it wasn't for me.

Personally, it's convenient with balancing work life, my family, and time for myself. Thanks Brandon and Ceze!!

The no-class-time model is incredibly efficient for a busy schedule; I never have to stress about a clock, I just show up and get to work. What makes this place truly special, however, is the warm and inclusive atmosphere: A Personal Touch: From the moment you walk in, you're greeted by name. There is a genuine culture of kindness where members cheer each other on through every round. Celebrating Milestones: One of my favorite parts is how we celebrate each other's progress. Whether it's a 100-workout milestone or a 500-workout achievement, the trainers and members make sure your hard work is recognized. Expert Coaching: The trainers are the perfect blend of professional and encouraging. They provide expert technical guidance while ensuring you feel motivated to push past your limits.

Selena has been kicking my ass all up and down this gym…read more I've taken many boxing classes before, but this is my first time ever having a woman as my coach and I must say that it became 10x harder versus a guy. I've gotten better with my stance, formation, breathing, etc. and I thoroughly enjoy the 1.5 hour workout. The bootcamp is the most intense and strenuous that I've ever experienced in all my years of working out and I love every painful and exhausting minute of it. Other notes: -Everyone is super skilled, strong and friendly. -The classes will have you in your best shape yet. -Selena has given me so many tips and important info on workouts, training and eating that are helping me reach my goal.

I've been to three different kickboxing/ mma gyms in Hayward but I really wanted to focus on real boxing. Despite the name, thats what US Karate & Boxing offers. Ive been training here for almost 3 years now and I can honestly say it has helped shape me into a more confident and healthy person. All thanks to Coach Joe and his son Coach Caleb. They have taught me so much and have helped me improve since the first day I walked in. They prioritize technique and take time to focus on everyone. They have different time slots for different skill levels, so you never feel overwhelmed. Each class usually consists of warm up, conditioning, drills, then light sparring but sparring is optional if you only want to work out. There are currently two amateur fighters, in the gym so if you're looking to compete then look no further. A membership includes two classes a week, and access to the gym outside of your training sessions. They have a ring, heavy bags, and a squat rack. It is a pretty small facility but its perfect if you don't care about the latest training equipment and want that old school boxing gym vibe. Training at US Karate & Boxing has easily been one of the best choices I've made, and I will continue to train here for the foreseeable future.

My son attends Kajukenbo on Tuesdays and Thursdays from 5:30-6:30 PM, and I've taken full advantage of the fitness classes offered during the same time. I'm incredibly grateful for the knowledge, guidance, and encouragement shared by the leaders at Dragons Den. It's been such a blessing to have an opportunity to invest in my own health and wellness while my son does the same. What makes Dragons Den so special is that it goes beyond the gym. The confidence my son has gained through the encouragement and support of this community has been amazing to witness. From the classes to the activities outside the gym, including the women's self-defense class that I've truly enjoyed, there are so many opportunities to grow, connect, and build meaningful relationships. Dragons Den is more than a martial arts gym - it's Ohana! We're so grateful to be part of a community that pours into its members both on and off the mat. If you're looking for a place where you and your family can grow stronger physically, mentally, and emotionally while being surrounded by people who genuinely care, Dragons Den MMA is the place to be!
