pegg looks like a powerlifter (no shit), ed looks like he does a lot of bodyweight exercises, alex looks like one of those guys that used to lift like crazy in college but stopped after he graduated back in 99, the other two look like they're just naturally in shape and don't really do much outside of playing basketball on the weekends.
that's just based on looking at one picture that wasn't exactly flattering, so it ain't a comment on those guys in general, just how it looks there.
