an insect named Derik won. at 5'2 180lbs he did 405lbs squat for 20 - according to the posts I've read. Some other gentleman did 600lbs for 10.
"Let's think about what the word equivalent means. If for an ant to lift 10 times its weight is "equivalent" to, or the same as, a human lifting 10 times its weight, then that must mean that if an ant were to grow as big as a human it would still be able to lift 10 times its weight. In other words, a 200 pound ant could lift 2000 pounds over its head. I can guarantee that that would not be the case. In fact, I am fairly sure that the poor confused giant ant would not even be able to walk or move, much less lift anything. And the same is true for the mighty flea. A flea the size of a human, in addition to being really gross and ugly, would probably not be able to budge itself, much less jump. I think it might rip its legs off if it tried to jump."
