Modern jiu-jitsu is a martial art that focuses on ground fighting and submission grappling. It emphasizes techniques such as joint locks and chokeholds, allowing a smaller person to defend against a larger opponent. This style has evolved significantly, incorporating elements from various grappling arts and adapting to contemporary training methods. In recent years, modern jiu-jitsu has gained popularity through competitions like the IBJJF World Championships and the rise of mixed martial arts (MMA). Training often includes drilling techniques, sparring, and strategy discussions, fostering a community that values skill development and mutual respect among practitioners.
