Gorillas are incredibly strong animals, with strength estimates ranging from about 4 to 10 times that of an average human. Fully grown silverback gorillas, the dominant males, can lift or exert force far beyond human capabilities. For example, a silverback gorilla can bench press up to 4,000 pounds (1,810 kg), while a well-trained human can lift around 885 pounds (401.5 kg)
. In terms of lifting power, gorillas can lift or throw weights up to 450–815 kilograms (about 1,000 to 1,800 pounds), which is significantly more than even strong humans
. Their upper body strength is especially notable, with the ability to exert pulling forces over 1,800 pounds (816 kg)
. Gorillas also have a bite force of around 1,300 pounds per square inch (PSI), nearly double that of a human, allowing them to crush tough vegetation and defend themselves effectively
. Their muscular build, fast-twitch muscle fibers, and high testosterone levels contribute to their explosive power and overall strength
. In summary, gorillas are estimated to be roughly 4 to 10 times stronger than the average human, with silverbacks being stronger than 20 adult humans combined in raw strength. Their strength is evident in their ability to lift thousands of pounds, snap trees, and exert tremendous force in bites and punches
