Have you heard of the tibialis posterior muscle? From an anatomical perspective, it plays a fascinating role in the human body. Originating in the lower leg and wrapping under the arch of the foot, it supports the load placed on the plantar fascia during movement. Whenever you’re running, jumping, walking, or anything in between, the tibialis posterior eccentrically contracts to control pronation through the foot.

In layman’s terms, this muscle is crucial for foot and Achilles tendon health, but very few train it…or even know it exists. As many of you are now aware, with neglected tissues comes pain and injury risks. For many individuals who aren’t taking care of this area, the plantar fascia gets overloaded with more stress than it can handle.

Over an extended period, or with repetitive activity, this stress can quickly turn into debilitating pain. This can then cause forced compensations in the gait, leading to complications further up the kinetic chain. Once one dives deeper into the anatomy, it’s easy to see why so many runners and endurance-based athletes get sidelined with foot injuries and more.
