A tendon, also known as a sinew, is a tough fibrous connective tissue band that binds muscle to bone and can withstand stress.
Ligaments and tendons are both composed of collagen, but ligaments bind one bone to another, while tendons connect muscle to bone.
Tendons and ligaments are both made up of protein. Collagen strengthens the tissues, while elastin, a protein found in ligaments, gives them some elasticity. Your body will produce new collagen and elastin as a result of the protein in your diet, which helps to keep your tendons and ligaments healthy.
Symptoms of weak tendons include:
Struggle to lift weights
Sound or feel of a pop or snap at joints
severe joint pain
Struggle to move
Struggle to bear any weights on joints
