      He’s mid-flex while running hard. Runners are slimly built (although sprinters less so), but what is there is pure muscle.

        What you are describing is being ripped, not jacked. He is indeed very ripped irl, but not jacked

        Being ripped: Having low amounts of bodyfat so your muscles have visible striations and vasularity

        Being jacked: Having lots of muscle mass, regardless of definition.

        Having so much upper body mass would be a disadvantage for a sprinter

          TIL they aren’t just synonyms, as slang.

          A quick image search turns up kind of the same thing in every running shot - at the very least his shoulders are huge - and you can see it a bit as he does his signature pose, as well. It makes sense to me - he, and sprinters in general use their arms quite a bit. Running has to be a whole-body process to be efficient; a cyclist couldn’t do it the same way.

          He does look pretty thin around the midsection in everything, though. And yeah, this image might be AI, or just photoshop.

        It is an interesting question though, would he be even faster if he weighed less from having smaller shoulders and biceps? Or are those muscles contributing to his speed.

          They are definitely contributing to his speed. At that level, people are shaped exactly how they need to be, and if you watch him run, there’s a whole lot of arm motion. AFAIK it’s basically the legs getting leverage against the arm’s opposing swing.
