Hi
I think they are based on the originals – GymJones (http://www.gymjones.com) They focus alot on endurance type and Combat sports and are run on the fight club principle. I do enjoy some of the concepts from GymJones as part of our Off-season setup; Sled-pulls, Sloshpipes, Rope Climbing & Med. ball work e.g. the stuff that can be done outside to break the monotonous and somtimes stale routines performed in the gym.
