With each footfall during running, the chain reaction between our body, the ground, and gravity begins from the ground up. This means that core stability starts at the foot and moves up through the knee, hip, pelvis, and then the spine. If there is a weak link in the chain, stability above that link cannot happen. For example, if the hip is weak, strong abdominals are not enough to compensate. Our abdominals require a stable pelvis to complete their task of keeping us erect while providing rotation of the spine to keep the opposite arm and leg moving forward.
Gluteals are the dominant controlling musculature of the hip. The deeper gluteal muscles (gluteus medius and minimus) control the lateral (side to side) and rotational positioning of the pelvis on top of our legs. By controlling the pelvis, the glutes are also controlling our center of mass. Running is a motion dominated by a forward direction, but it also contains lateral and rotational components. These components are often neglected in training, thus fostering an imbalance and further exploiting any weaknesses. This results in inefficiencies, numerous injuries, or sometimes just the inability to maintain good running form, especially later in a run.
