Before Jiu Jitsu, we tried several activities, but nothing really stuck. Our daughter felt shy and uncomfortable in most environments. From day one here, Sensei Sam made her feel welcome and part of the group. That care and encouragement meant everything. Now, three years later, the change is incredible. She's more confident, more focused, calmer, and makes better decisions. Her social skills have improved so much, and she's not afraid to step into new situations anymore. She carries herself differently -- stronger and more self-assured. And the best part? She absolutely loves going. This isn't just martial arts training -- it's character building, teamwork, and life skills. We're very grateful we found this place. Highly recommend to any parents considering it.

I've been training Muay Thai at USKO Riverside for almost two years. This studio is run by the…read morePagliuso family where Joey fought in Kickboxing and some Muay Thai. The evening classes that I attend are taught by lead instructor, Ray. Although I only train in Muay Thai, Brazilian Jiu Jitsu and Karate classes are also offered here. Onsite gym access is also offered with Gold membership and access to the Orange facility is also offered with the Gold membership. Muay Thai practices typically consist of a warm-up such as jump rope or jumping with conditioning drills in-between, shadow boxing, learning technique by hitting pads, bag drills with punches and kicks and sparring at the last 15 minutes of practice. The workout is great for me as I'm in my 50's and I don't have any aspirations to compete. I attend 2 - 3 times a week, evenings during the week and sometimes Saturday morning. It would be tough to get that high intensity workout by just going to a gym. The staff is is friendly and helpful. My only opportunities for improvement are more clinch training is needed on Monday or Fridays and the mats could be cleaned more frequently. Four stars!

I liked that the class consisted of a lot of partner drills and pad work, with the option of sparring after every class. I signed up on the spot for a twice a week membership. A few months later I tried out the jiujitsu class with coach Paul and got hooked on that as well. My first class we worked on one move then rolled for the rest of class. It was a great workout and no information overload from trying to learn too many techniques in one class. I upgraded to the unlimited membership after that class.
