9 Round Boynton Beach

Shannon "The Cannon" Hudson is an International Kickboxing Federation world champion, a fifth-degree black belt in japanese shotokan karate, and a survivor of more than 70 bouts in the ring—yet, one of his most influential titles is "father." With two kids clinging around his waist like a squirmy fanny pack, Shannon started brainstorming a way to channel his boxing and kickboxing training into a quick, effective workout that even those who are busy or out of shape could tackle. The result was 9Round, a 30-minute routine of aerobic, anaerobic, and resistance moves divided into a circuit of nine stations. The ever-changing series of workouts maximizes morale and results and minimizes boredom.

His trainers launch the workouts every three minutes, motivating exercisers through each station—which might include jumping rope or pummeling speed bags. Online nutritional counseling supplements the workouts, teaching patrons how to construct and eat healthful meals instead of falling back on old habits, such as snacking on cheese sculptures.
