Slightly speculative question, and probably impossible to answer accurately. Just a bit of fun and something to aim for. Taking the general population, what percentage do you reckon can pull 500 lbs or above in the deadlift? Not theoretically pull if they trained. But right now, as a measure of strength, are able to pull 500 lbs. I can't see it being more than 1 in 100 (1%) and probably considerably less. I think I've seen one person do it at my gym, which has a membership in the hundreds. Even on this forum, with plenty of strong people who train seriously, I wonder how many can pull 500 lbs.
