Is extreame muscle group targeting ok?

[QiMaster]

Among other things I take judo. I know that when you practice a MA certain muscles are inebitably going to get stronger than the rest (I already see a difference in my grip). For the most part my musclse are proportionate (no outstanding bicepts or anything). Im wondering, is it a good idea to highly develop a certain group of muscles? Should i train evenly and simply let nature take its course if my body decides to bulk up in one area or another due to consistant use of my style? Or should i do physical training in an attempt to further it? I've seen some people that have done this and well. some of them look like they have a giant tumor instead of a tricept because it looks so improportionate from the rest of their arm.(Had a nice punch though)

Nope its not as that can **** you up. Try to maintain proper balance between groups.

Google compensatory training. You do not want muscle imbalances. It will only hurt your game and your health later on. Strive for balance over specialization.
