What are the odds of becoming a UFC fighter?

UFC takes people from lesser promotions. So i would recommend finding a good training camp near you. There are a lot of UFC fighter's gyms around the world. Most notable would be Sit yod tong in Boston, Greg Jackson in Arizona, American Top team Cali and Tampa. But wherever you are there should be a major camp near by. I recommend getting to a major camp that has had UFC fighters before. Get into local productions win fast and make it a show. The UFC will come to you then.

Best of luck
