I just read a thread of men's strength vs women's but nowhere have I ever seen

in print is why the male human can work out and exercise and gain muscle mass, but a chimpanzee can work out climbing trees, swing from branches, etc. and never gain the muscle mass a human does, but is much stronger physically than the human.
Anyone know the answer to this?

1. No, but good question.

You will have to find someone a lot smarter than me to answer that. I'm guessing that diet has a lot to do with it.

never got an answer to my question. If a man did everything the chimpanzee did in a month's time, the man would have huge muscles..the chimpanzee's physique stays the same.
Even with similar diets, although the chimpanzee is more of a vegetarian.

5. if the humans had spent their entire lives "working out"

as the chimpanzees do, they wouldn't see an increase in muscle mass, either, because they would be living within the conditions that create the muscle mass from birth.

iow, with humans, they're coming out of a sedentary society. the increases indicate how much time they spend performing particular tasks.

muscle ability also depends upon how muscles are attached to bones, at what point, and for what purpose.

most four-legged animals of a certain size are faster than those animals that are bipedal. Their skeletal/muscle configurations make this reality from birth.

Humans and chimps have different anatomical structures, based upon the ways muscles are used.

8. It has more to do with how their muscles work. Not how big they are.

A male chimp is stronger than a comparable sized human male. However their overall bulk would appear the same.

In the case of measuring strength you need to look at the muscle fibers closest to the bones. Those muscles are deemed to be the source of strength of both chimps and humans. In a chimp those muscles in particular are much longer and more dense. So our furry friends are able to generate almost twice power with a longer range of motion. The downside for the chimp in that they lack the same muscle control that humans do. So a chimp will use more power than is actually necessary.

Their arms are designed differently and they have much more power for some tasks than we do. (And a pit bull has more jaw-psi than I do, despite being half my size)

Chimp grip is incredible. Their grasp is unbreakable. Their "curl" strength is awesome. All what one would expect from arms evolved to carry ones weight. And as hand-oriented creatures we put great stock in those strengths. We fight with our arms and we don't want to fight a chimp.

But you never see chimps lifting heavy things people cannot lift. They are not designed for that kind of lifting. (Perhaps they are impressed by human prowess when they see us carry things.)

If their muscles were intrinsically many times more powerful per gram then their little legs would be stronger than our legs. Are they? I'd doubt it.

I do know my cat displays phenomenal strength when I try to wrestle him into a carrier to go to the vet.

they do? Their muscles stay pretty much the same whether working out in the trees or not. A human's muscles would increase in size doing the same thing.

Their muscles are different from ours. Their muscles are longer and more dense.

Their muscles do increase in size, however due to the density overall it would not appear to gain much size.

Apes have a much higher muscle tensile strength then humans ever will. As for why, I have no idea.

weights when I was younger and seem to never gain muscle mass. I have noticed at the gym
many guys that look much stronger than me have little strength. Must have something to with the type of muscle.
A guy I worked with looked skinny but he could beat anyone in the department in arm wrestling and could eat like a horse
and never gain an ounce.

and trapezius attachments fore and aft; humans just have some slivery tendons from the back, and a two-inch-wide tendon for the pectorals

we're built like Gumby compared to the rest of mammals, who have a burly chest and "forelimbs": we compensate with GIANT, out-of-scale legs connected to this Rococo, three-dimensional pelvis that really protrudes ("Adam's girdle" for men) and has psoas muscles stuck through it, blocking the birth canal

that said, leg-wrestling with a chimp to see who's stronger would just horrify both parties
