The Achilles tendon is the strongest tendon in the body…and one of the most stressed.
It connects the calf muscles to the heel and plays a major role in walking, running, jumping, and pushing off the ground. Every step you take loads this structure.
Because of that constant demand, the Achilles is prone to overuse, tightness, and injury, especially with sudden increases in activity or poor calf flexibility.
Understanding what it does helps explain why even simple movements can become painful when it is irritated.
