Alexander Crispim, the muscular, prolific leader of Crispim BJJ Barra Brothers, presides over his blue-floored kingdom, watching as patrons battle one another with traditional brazilian jujitsu grappling techniques. Rows of heavy, black punching bags dangle between padded walls, all centered around the gym's main draw—the MMA cage, which is free of man-eating tigers. In addition to jujitsu, the gym offers a variety of combat-based programs including muay thai, boxing, and wrestling. Those looking for a high-intensity workout without the sparring can opt for MMA fitness classes, which turn traditional boxing and muay thai moves into aerobic routines to burn fat and build strength.
