I did much more than 10 push-ups or 7 min circuit training each session for those six months (and those six months isn't the only time I've exercised, just one of the longer uninterrupted streaks of it). Don't patronize me.
Not trying to patronize you at all, and I apologize if it came off that way. I'd say that most people in the tech/hacker community aren't too well acquainted with consistent, dedicated exercise. It wouldn't be unreasonable for someone to have the belief that after 6 months of 7 minute circuits, their body should be well adapted to intense workouts. Since I don't know who you are or where you stand on the experience spectrum, I took an educated guess, and apparently was wrong.
