You say you don't like apple and orange comparisons?
The whole thing of comparing human and monkey strength is an apple/orange thing altogether. A monkey/ape's arms are his major limbs. You can't compare an ape's arms to ours; the natural comparison is the ape's arms to our legs. Want to see how lame a chimp really is? Have him try to run a competetive 440. I once saw Kazmaier pick up an upright freezer and RUN up a hill with it; it's far from obvious, to me at any rate, that a gorilla could do that.
Likewise there used to be a guy with an orangutan who would show up with the carnival around where I live offering $50 to anybody who could stay in a ring with the orang for two minutes; the SPCA made the guy drop the act after some karate artist all but killed the orang without getting touched.
But the real comparison here is between human weightlifters and pure herbivores such as the sauropod dinosaurs, horses, cows etc. If animal muscle were 10 times better than ours as the one person cllaimed, than it should be no problem to demonstrate some 360-lb herbivore lifting the same 1000-lb. weight which Kazmaier used to do squats and deadlifts with. In real life, the first time you get to a herbivore which can do anything at all with a 1000-lb. load other than get mashed flat by it, you're talking about elephants.
