Many jiu-jitsu schools claim some connection to the Gracie family, a legendary clan of Brazilian fighters whose unique martial arts style continues to reign supreme in famous no-holds-barred confrontations, such as the Ultimate Fighting Competition (UFC). But South Florida has only one school with official accreditation from Helio Gracie himself, founder of the sport and father of an entire family of world-class fighters. Brazilian jiu-jitsu's mix of judo with simple and effective ground-grappling techniques proves incredibly effective against larger and stronger opponents. Small, soft-spoken instructor Pedro Valente, who was a student of Helio Gracie, makes this point painfully clear. At first glance he is unlikely to inspire fear in an opponent, yet his submission hold can bring down just about any once-aggressive rival. Valente's method for strategic conquest, while certainly not easy, is a lot less strenuous than, say, pumping major iron. And for what? Beefcakes, beware: Think twice before picking on some little guy. He just may have been trained at Gracie Jiu-Jitsu. Ouch!
