I'd say more like less than 0.001% of people.
When I came out of college (played football) I went into competition BB & powerlifting. I could bench 325 clean but could barely run a 10 min mile. Lol
After about 10 yrs of this, I transitioned to running & shed 35 lbs! (200 to 165). It took me a few years to get to the point where I could break 7 in the mile. I was still lifting somewhat but not BB or powerlifting training. My bench was barely 225.
If there's a guy out there who can bench 250 and run a sub-7 - that would be hard to believe - and I would be suspicious that PEDs were involved. 😉
