Mixed martial arts network looks to double its gym locations.

The Ultimate Fighting Championship Gym franchise is aggressively expanding in the U.S. and Canada with plans to open more than 100 new locations this year.

Based on the tenants of the mixed-martial arts network and its star athletes, each UFC gym lets members spar inside the Octagon (the octagonal fighting ring used in UFC competitions). The gyms also feature adult and youth training in jiu-jitsu and wrestling, mat room workouts, various fitness and exercise programs, Ultimate Training and Functional Fitness classes, as well as private coaching and one-on-one training.

There are currently more than 120 UFC Gym locations in 25 U.S. states, as well as in Australia, and Philip Jacobs, director of franchise development for UFC, hopes to add 150 new franchising commitments from existing franchisees and 125 committees from outside prospects over the next few years.
