Classes & Training
Whether your goal is to compete, get in shape, learn self-defense, or just have fun — our classes will help you reach all of them. Every new member gets a one-class free trial.
Brazilian Jiu-Jitsu focuses on grappling and ground fighting — using technique and leverage so a smaller person can control a bigger, stronger opponent. We train for both self-defense and sport. Most classes are taught by 1st Degree BJJ Black Belt William Krieg, and all levels are welcome, from first-timers to experienced grapplers. A gi is required after your free trial class (sold at the gym).

A fun way for boys and girls to reach fitness goals while building focus, self-discipline, and social skills they'll carry for life. Classes are structured to challenge kids, with strong positive reinforcement when goals are reached. No equipment needed for the free trial class — a gi is required once they continue (sold at the gym).

Lace up your gloves for an invigorating workout combining cardio, strength training, and the art of boxing. Classes mix conditioning drills, technical training, and controlled sparring with headgear and gloves — all skill levels welcome, beginners always. Students will want gloves, hand wraps, and a mouthguard once they continue.

Unique self-defense training for men and women — brought to your group or business rather than held on a fixed gym schedule. Classes are taught to groups at your facility to address the specific needs of attendees, or at Flashback Martial Arts when a suitable location isn't available.
