But building muscles is also a sports skill. That's what bodybuilding is about. And the difference in training is a pretty small factor in most sports. While training is important, genetics is by far the most dominant factor.
I'm guessing you've never been an athlete, have you? Look, my spouse is 6'2", 210 lbs, with very dense bone structure. But if you put him in a ring with an MMA fighter who is 6'2", 210 lbs, he will get his ass thoroughly whooped. Training is a significant difference when it comes to performance. Some of the underlying physical elements add benefits that are extraneous to training - a 6'2" person will have greater reach than a 5'0" person... and there is nothing that training can do to alleviate that.
I've trained a variety of of martial arts most of my life, as well as other sports. I'm right now in an incredibly good shape. I know how training works. A smaller trained person can beat an untrained bigger person. But if both are trained the edge of the bigger person tends to win out regardless of skill level.
I remember a guy in my BJJ club who was a circus strongman as well as an alcoholic. He wasn't particularly good technically, and often drunk during training, still won almost every time only down to sheer strength. He often beat our incredibly skilled and strong trainer. Because he was so damn massive. I've never been particularly muscular (relative to other MMA fighters), so I know the importance of muscles.
