A common saying is that there is no MMA without TMA. The MMA guys have invented nothing. MMA is just a way of training, you train to be proficent in every range possible in unarmed combat (standup, clinch/close and ground). No matter wath you´re training in, you must ask yourself what is your purpose, that is, why you´re training. If you´re doing MA to improve your general fitness condition, almost any style or training method would suffice. But if you train to learn to fight (that is, defend yourself) you´ll have to fight. You learn to write by writing, you learn to drive by driving, you learn to play guitar by playing guitar. So, if you wannna learn to fight, eventually you´ll have to. Now, the sportive part of MMA needs to ensure a minimun safety environment for his practicioners. Thus, enter the gloves, enter the mouthguards, the cups, the mats, referees, etc. But nonetheless, MMA is the closest approach to a real fight that exist nowadays.
