Why don’t tendons tear when a person lifts heavy objects?

Tendon is a connective tissue. They fix the places where muscles attach to bones. Tendons are made up of many fibers. A person, in order to lift a certain load, makes efforts and uses his own strength. The main job of the tendons is to “transfer” some of the strength to the muscles for relief. However, the tendons themselves are quite strong, as they have a spiral structure. The tendons can support 500-1000kg / cm2.
