Can the Chin be Trained?

The more I examine the question of ‘can the chin be developed’, I think ‘a chin’ can be developed. When I refer to ‘a chin’ I mean the relative ease of a fighters ability to absorb a punch with out being effected greatly. Obviously things like location , velocity, power of a punch or kick can potentially KO anybody. However it is clear that it takes more to KO some fighters over others.

When anyone first starts to train MMA punching(knuckles), kicking(shins), BJJ(flexibility) causes much pain the respective areas of the body because the body is not used to the punishment. After weeks and months of punching and kicking, or rolling around on the ground, the nerves in the hands and shin get used to the pain and the body gets more flexible. I believe the ‘chin’ will react in a similar manner, in that the body will react and become accustomed to the pain. This point is difficult to prove, because not many people want to train every day with out head gear repeatedly taking shots to the chin/face! I haven’t had the opportunity to visit many training camps, but was surprised when watching the last UFC All Access with Wanderlei Silva, and WAND sparred with out any head gear! I thought to myself that’s crazy tough! After watching WAND take the punches from Chuck during their match and not go down, I realized the chin can probably be trained. The question is, who is willing to train their chin…
