Checkmat Corona BJJ is a great place to train jiu-jitsu with a super cool environment and a sense of community that feels like a second home or family. The training is intense and the instructors are very knowledgeable, hands-on, and genuinely care about the students. Professor Jimmy is exceptionally knowledgeable with a deep understanding of jiu-jitsu, competes himself, and is always willing to help. Professor Cindy has built an amazing women’s program. The academy offers both morning and evening classes, a flexible schedule, and a nice facility. They have a great kids’ program with regular and competition classes, which has grown significantly. The camaraderie is incredible, with a supportive atmosphere where everyone, including parents and kids, supports each other. It is friendly for everybody, whether for a hobby, personal defense, or competition. Highly recommend checking them out; they offer a free trial.
