How come gorillas are so muscular without working out and on a diet of mostly leaves and fruits?

>>76640132 (OP)
1. Genetics & muscle fiber composition

Gorillas (and other great apes) are genetically wired to carry far more muscle mass than humans.

They have a higher proportion of fast-twitch (Type II) fibers, which are thicker and generate more force than the slow-twitch fibers humans use heavily for endurance.

Their baseline testosterone and growth hormone levels are also higher than ours, which drives greater natural hypertrophy (muscle growth).


2. Strength prioritized over endurance

Humans evolved for long-distance running, throwing, and endurance. Gorillas evolved for climbing, fighting, and short bursts of incredible strength.

Evolution "chose" strength for them and efficiency/endurance for us.


3. Diet and digestion

While gorillas eat plants, they eat massive amounts — about 40–60 lbs (18–27 kg) of vegetation daily.

Their gut is specialized: the large hindgut ferments plant fiber into short-chain fatty acids (like acetate, butyrate, propionate), which provide calories and building blocks for muscle.

They’re not eating "salads" like humans do — they’re getting high-calorie, protein-containing plant matter (leaves, stems, shoots, fruit, bark).


4. Constant activity

Wild gorillas spend most of the day foraging, climbing, and moving heavy weight (their own massive bodies).

Even without “training,” that’s essentially resistance exercise all day, every day.


5. Scale advantage

Muscle strength doesn’t increase linearly with size — larger animals have disproportionately stronger muscles simply because of cross-sectional area scaling. Gorillas weigh 300–450 lbs, so even "normal" muscle tone on that frame looks massive compared to a human.


So in short: gorillas are naturally muscular because evolution gave them the hormones, muscle fibers, and digestive system to grow huge on plants — plus they live a physically demanding lifestyle.

i mean what are the delts for, lifting his bro into a tree to grab monkeys

Why their penises small though?

1. Sexual selection pressures differ between species

In species like humans and chimpanzees, sperm competition (multiple males potentially mating with the same female) was an evolutionary factor. This tends to select for larger testes (to make more sperm) and, in some cases, slightly larger penis size to help deposit sperm more effectively.

Gorillas, on the other hand, live in harems (one dominant male controls access to several females). Since the dominant silverback largely monopolizes mating, there’s little sperm competition. Evolution didn’t “care” about making them bigger in that area.


2. Energy allocation

Evolution favors efficiency: gorillas are investing resources into bulk, strength, and dominance displays — the traits that actually determine who gets to reproduce. A 400-lb muscular frame intimidates rivals and secures mates more effectively than a larger penis would.


3. Testes size matches the story

Gorillas have very small testes relative to body size, much smaller than chimps. This reflects their low sperm competition. Humans are in between: we don’t have chimp-level sperm wars, but we also aren’t harem-exclusive like gorillas.


4. It’s all about mating system, not absolute body size

For context:

Gorilla penis: ~1.25 inches (3 cm) when flaccid, ~3 inches (7.5 cm) erect.

Human penis: ~5–6 inches (13–15 cm) erect on average.

Chimp penis: ~5 inches (13 cm) despite chimps being much smaller than gorillas.
So basically: gorillas don’t “need” a large penis because sexual competition isn’t about sperm delivery — it’s about fighting off rivals. Evolution built them like tanks, not like… well, chimps.

Would you like me to map out a side-by-side comparison of penis size, testes size, and mating system across humans, chimps, bonobos, and gorillas? It makes the pattern really clear.

That's what I need a mating system

How do they even penetrate? How do they stay in? No way can they manage to stick for cowgirl.

Here’s a clean comparison across the four main great apes, including humans:

Mating System vs. Genital Traits

Species Typical Mating System Penis Size (erect) Testes Size (relative to body) Why This Pattern Exists

Gorilla Harem (1 male, many females) ~3 in (7.5 cm) Very small One dominant male monopolizes mates no sperm competition evolution favors strength, not genital size.
Chimpanzee Promiscuous (many males, many females) ~5 in (13 cm) Very large Intense sperm competition bigger testes to produce more sperm. Penis also relatively large despite small body size.
Bonobo Highly promiscuous, social-sexual bonding ~4.5 in (11–12 cm) Large Sex used for social cohesion frequent mating sperm competition still important.
Human Mixed (pair-bonding + some multi-male/female overlap historically) ~5–6 in (13–15 cm) Medium Humans aren’t strictly monogamous or promiscuous moderate sperm competition penis relatively long/thick compared to apes, testes mid-sized.

Key pattern:

Harem system (gorillas): No sperm wars tiny testes + small penis.

Promiscuous system (chimps/bonobos): Lots of sperm wars large testes, relatively bigger penis.

Humans: Somewhere in between moderate testes, relatively large penis (especially in girth compared to other apes).

You ready for the sperm wars?

People rip on creationists and their fiction, however, evolutionists make just as great fiction writers too (and penis afficionados to boot).

Good question — it sounds puzzling at first since gorillas are massive animals with relatively small penises. But the anatomy and mating behavior make it work just fine:

1. Gorilla penis size is “small” only in comparison to body size.

Erect length is ~7.5 cm (3 in), which is still long enough to reach the female’s reproductive tract.

Female gorillas are smaller than males (100–250 lbs vs. 300–450 lbs), and their genital anatomy is proportioned for the males’ size.


2. Mating position makes penetration easier.

Gorillas usually mate in the dorsal-ventral (male behind female, like quadrupeds) or ventro-ventral (face-to-face, rare but observed) positions.

Because the female’s body is angled in a way that exposes the vulva, the short penis length is sufficient.


3. Reproductive strategy doesn’t require long penetration.

In gorillas, the key to reproduction is monopolizing females through dominance, not inseminating against rival sperm (like chimps).

Once the alpha male gets access, there’s no competition — so deep penetration or large ejaculates aren’t critical.


4. Ejaculate and fertility efficiency.

Even with a smaller penis, gorilla semen is sufficient to fertilize because the female tract and cycle are aligned to it.

Evolution shapes compatibility, not size comparisons across species.


So basically: gorillas penetrate and reproduce effectively because their penis-to-female anatomy is matched, and their mating system doesn’t demand extra size.

Do you want me to also explain how gorilla mating behavior (timing, frequency, female choice) ensures pregnancy despite the “small” anatomy?

they're actually not

Do you guys think female gorillas are impressed when they see a naked human male? I would love to show my erect penis to one of them to see how they react to it

Gorillas ferment plant matter into saturated fat, fucking chuds

Herbivores mostly evolve one of two defense mechanisms. Either to be good at spotting the predator and running the fuck away, or be big and strong enough so that predators don't fuck with you.

Humans on the other hand evolved to throw rock, which happens to be the meta.

You'd get degloved, anon. Look up that lazy who got chimped. Or the gorilla war documented by that ape woman.

Apparently they just sort of "spray" in there.
Human anatomy is rather different as I imagine your aware.

The size of our balls actually disproves the bullshit that monogamy and posessiveness are social constructs. Its not at all. It corroborates what weve always known. We dont operate in absolutes when it comes to mating and sexuality but trending more towards monogamy

I learned in 6th grade about sperm competition and that women sometimes have multiple partners' sperm competing at once.
