Why are you all buying into the same nerd-jock dichotomy from junior high? Exercising or taking up a sport won't lower your IQ 30 points or make you unable to write a C program. You should have more in your life than sitting in front of a blinking screen, snacking and anime porn.
I'm an mechanical engineer and I also am a competitive powerlifter who holds state titles. Being at that level of sport requires a considerable time commitment, but It's something that I enjoy. I remember the first time I tried incline benching; I got pinned under 95lbs. Now, I can rep 365lbs. I would never have discovered this ability if I just looked at exercise and strength as something for dumb jocks who are mentally enfeebled.
