Check out the master mind behind
Erik’s system (CSW) blends Judo, Freestyle Wrestling, and Greco-Roman Wrestling with techniques and submissions from Shootwrestling, Brazilian Jiu-Jitsu, Sambo, and Catchascatchcan. CSW trains the individual to strike, clinch, takedown, and submit on the ground in either a sport, mixed martial art, or self-defense environment. It is laden with painful submission hold and a plethora of devastating leg locks. The evolved style provides the perfect compliment to Brazilian Jiu-Jitsu. Hahn Coaches are under this system.
