I'm trying to get in good shape. Should I enter into a BJJ/Martial Arts/MMA school or go to 24 hr fitness. The Octagon in Dallas is ran under one of the best MMA fighters around (look it up). It also has training equipment, like weights, punching bags, personal trainers etc, but it is kinda pricey. 24 hr fitness is a little cheaper i think but some people say it is crowded. I want a place where they take things serious, not some aerobics crap. What do you think?
