I only recently started training and I was what in most sports would be labeled Bantam or even less. And I wrestled with guys almost literally double my weight and I won. Some who had quite a bit of Martial arts experience some who didnt. Actually one of two guys I lost to was a judoka. So from my experience it's best to not do martial arts, to weigh as little as possible, to not train your muscles if you want to win wrestling games. And if you do want to train, pick Judo.

Of course we all know that isn't true, but that shows what personal experience can do.
