Similar to Brazilian Jiu-Jitsu but practiced in shorts and a fitted shirt (rash guard), submission grappling focuses on joint locks, chokes, and gaining dominant positions. The action is typically fast and quick. Submission grappling uses leverage, body mechanics, balance, speed and technique to dominate and submit an opponent. The Submission Grappling Program at Bangkok Fight Lab is based on No Gi Brazilian Jiu-Jitsu, Sambo, Pankration and other submission arts. Advanced submission grappling skills are essential to compete effectively in MMA fighting.
