Today's mixed martial artists come from all corners of the globe, trained in diverse disciplines from Brazilian Jiu-Jitsu to Boxing, Karate to Krav Maga, San Shou to Sambo. They compete in nine main weight classes: flyweight (125 lbs.), bantamweight (135 lbs.), featherweight (145 lbs.), lightweight (155 lbs.), welterweight (170 lbs.), middleweight (185 lbs.), light-heavyweight (205 lbs.), heavyweight (265 lbs.) and super-heavyweight (265+ lbs.).
Most career MMA fighters strive to reach the "big leagues" of the Ultimate Fighting Championship, though a number of alternatives and feeder leagues to the UFC - such as Strikeforce, Bellator, and DREAM - have given fighters increasing options in recent years. For fighters under 155 pounds, the premier destination is World Extreme Cagefighting (WEC), a Zuffa-owned promotion with a focus on bantam-, feather- and lightweights.
