According to Sea World, a gorilla has six times the upper body strength of an adult human. Assuming an average person can bench press his body weight, a 300-pound gorilla is capable of pressing approximately 1,800 pounds.
The upper bodies of gorillas are enormously developed compared to humans because gorillas use their arms for walking and climbing. Gorillas are the largest primates in the world and live in tropical and subtropical forests of Africa. Three subtypes exist: the mountain gorilla, the western lowland gorilla, and the eastern lowland gorilla. Although gorillas are formidable, they are peaceful by nature and subsist on diets of foliage and fruits. Gorillas live in complex social structures called troops and are led by an alpha male, who is also called the silverback.
