How about those old lady's who leap into action and DL/hold up a car, while people drag a little kid out from under it? Holding it up for over a minute, at times. And in most all cases, even after a few days, they might feel a little sore but no big deal. No pulled ligaments, tendons or muscles. Even in the lower back area.
If a chimpanzee is estimated to be at least 8 to 10 times &guy as a normal adult man, with much less bwt, than how strong could a human really be. Guy's and women on PCP/Angles Dust can be extremely strong, breaking cuff's at will. And they normally are skinny and look like walking death. Time for those 2000lb Dl's and squats to be a common thing if the mind set is right. How about throwing a little kid under a DL bar for motivation and world records?
Side Bar: used to push up hill and front/rear bumper DL an old Jeep Wrangler. But that was pretty light. Had to some times when caught in loose sand. Fun any way.
