FWIW, I've worked with numerous "high-level developers" who were quite fit. Not all of them had 19" biceps like this guy, but they were all pretty athletic. I'm talking a former pro cyclists, a jujitsu coach, someone who competed Iron Man competitions well into his 50s, an ultra marathon runner, a parkour gym owner, a pro tag player (yes this is a thing), a competitive TKD sparrer, plus lots of people who work out everyday just to be healthy. My last job had a team "strong man" board where people would post up their bench/deadlift/squat numbers.
It's pretty common for great developers to have interests outside of computers.
Edit: I'm sorry again. This article was about things you can do to present yourself well and all I'm saying is that I wouldn't hire him based his profile picture.
The content of the article had plenty to criticize.
I'm sorry for making racist comments against the aliens from Galactus 5. I was just worried about how the aliens from Galactus 5 are stupid ugly aliens. I won't let my fear of the crazy stupid aliens from Galactus 5 get to me, I'm sure they are good programmers.
