A silverback gorilla can lift approximately between 815 kg (about 1,796 lbs) and up to 1,810 kg (around 4,000 lbs) depending on the source and the type of lift measured. Estimates suggest:
- A silverback gorilla can bench press up to 4,000 lbs (1,810 kg) according to some claims, which is nearly five times the bench press of a well-trained human (around 885 lbs)
- More conservative and researched estimates indicate a silverback can deadlift or lift around 815 kg (1,796 lbs), which is still about 4 to 9 times stronger than an average human
- Theoretical calculations based on muscle force output suggest a bench press capability around 925 lbs (419 kg) for a 185 kg gorilla
Overall, silverback gorillas are estimated to be roughly 4 to 10 times stronger than the average human, capable of lifting or throwing weights well beyond human limits, with their strength supported by dense muscle fibers, powerful arms, and evolutionary adaptations for climbing and defense
. In summary, a silverback gorilla can lift roughly between 800 kg to 1,800+ kg, with the higher figures often cited but sometimes debated. Their strength far exceeds that of humans, making them one of the strongest animals relative to body size.
