• Ages: 8–18 years old
Steel MMA opened in 2016 with a stated conviction that authentic Muay Thai, BJJ, and MMA training that produces champions should not be limited to experienced fighters. The gym describes itself as San Diego’s most authentic Muay Thai, BJJ, and MMA gym, with a culture based on authenticity, respect, growth, community, and accessibility. The program states that nearly every student started with no background or fitness base and that the average student has been training there for over four years.
The BJJ coaches at Steel MMA have competed and trained at high levels and have worked with professional athletes who have competed in organizations such as the UFC, Bellator, InvictaFC, Glory Kickboxing, Lion Fight, IFMA, World Games, and OneFC. Coaches at the gym, including professional athletes and coaches such as Hiro, Z, and Carl, have trained students who have competed at national and world championship levels across Muay Thai, Kickboxing, BJJ, and MMA.
Steel MMA provides martial arts classes to families from the San Diego, Tierrasanta, Mission Valley, Kearny Mesa, Serra Mesa, and Clairemont communities. The program reports that four years is the average time a member has been training at Steel, that 10% of members coach at another gym in San Diego County, and that 100% of members are described as being there for the “good vibes.”
Parent and student testimonials describe the coaches as professional, friendly, knowledgeable, and focused on student safety, and they mention both Muay Thai and BJJ coaching. Several testimonials refer to the atmosphere, the lack of an elitist vibe, and the presence of high-level, top-tier coaches, including Hiro, Z, and Carl. Multiple reviewers state that Steel MMA is the best gym they have trained at and that they would recommend it to others.
