Most of their limb strength is used to support their own body weights. In fact, gorillas have about 36.6% of their total muscle mass concentrated in their front limbs and about 42.5% in their hind limbs.ĭespite their strong limbs, gorillas cant reach high speeds, though. This type of movement explains the presence of strong muscles in both front and hind limbs. Bipedal movements are limited and generally only employed for eating or socialization purposes. For locomotion, gorillas use all four limbs as legs (knuckle-walking). LegsĪside from strong forelimbs, gorillas also have strong hind limbs. Comparatively, the average man has a hand size of 7.6×3.5 inches. In fact, a silverback gorilla has a hand size of about 12×6 inches. Not only are silverback gorillas the largest primates, but they also have very big hands.

There are no scientific studies, but considering that orangutans have a grip strength of about 600 pounds, it is safe to assume that gorillas are stronger than this. In addition to a strong punch, gorillas also have a strong grip. This force is similar to that of a Sumatran tiger. Based on their body weight and maximum speed, a gorillas punch can have an impact force of 12,500 lb.-ft./s. Similar to boxing, a gorillas punch force depends on its weight and velocity at the moment of the impact. However, this doesnt mean that gorillas go around throwing powerful punches.

Compared to the average man, silverback gorillas have a punch force about 30 times stronger.

Silverback gorillas have a punch force up to 2,700 pounds - strong enough to shatter bones with one slam.
