In high school, the only guy I knew who went to an Ivy League school was drafted by the Bears...got cut later on, but his degree in finance from freaking Princeton might help him with being successful in the world. Nicest guy I ever met, damn tough running back, and he was my tutor in AP Chemistry. Genius in science, mathematics, etc...
The guy who got me hooked in fantasy (George Martin, Star Wars, LOTR) was 6'2 and 245 lbs with a bench press that I couldn't even fathom at the time (I was not athletic, but I was winning trophies in shooting sports at the time as a high schooler, so I wasn't the typical nerd either). I knew it was more than three plates. The only athletic activity this guy couldn't do was rollerblading...which gave us all a chuckle to see his big ass rolling down a hill flailing his arms and running into everything that could be run into. He was a band kid...much to the consternation of the football coach, who saw this guy in conditioning and the powerlifting camps every season and practically got on his hands and knees and begged him to play for them. He never did. But then he did end up getting a degree in chemical engineering from Northwestern in Evantson. Pretty sure he works for some big company and takes home a fairly fat paycheck.
Nerds, as they are known by people who don't attend high school in a John Hughes movie, are a very diverse group, inclusive of many body types, personalities, and physiques. It is only the very insecure who seem to insist that just because one is intelligent, one cannot be physically strong or attractive or that just because one is physically strong or attractive, one cannot be intelligent.
