Foundations. Partnership. Results.
BMT KICKBOXING
BMT is a rigorously developed striking system created by Sensei Duane “Bang” Ludwig and informed by UFC Hall-of-Famer Bas Rutten. It incorporates elements of Muay Thai, Dutch Kickboxing, American Boxing, and traditional martial arts to culminate in a world-class striking system that has helped top MMA and UFC fighters such as TJ Dillashaw win championships.
KRAV MAGA
Krav Maga is a practical and tactical system that teaches how to prevent, deal with, and overcome all kinds of violence and attacks. It prepares students for real life self defense situations. Krav Maga techniques are based off of instinctive responses, which make them easier to learn. This program allows students to get fit while also learning skills and techniques that could one day save their life. This membership includes Boxing and Kickboxing classes.
