The vast majority of movements in Crossfit are functional compound movements and consequently focus on the major functional axis of the human body, the extension and flexion of the hips and torso or trunk. In this regard all Crossfit movements can be considered to focus on generating power from core to extremity. At the heart of this core to extremity concept is the focus on powerful hip extension, the opening of the hip. The hip extension predominantly leverages the glutes and hamstrings some of the largest muscles in the body.
A strong core lies at the heart of hip extension, forming a stable ‘bridge’ between the upper and lower body, Running, jumping, punching, and throwing all involve powerful core. Developing a strong core is not only essential for athletic progress, but also a primary focus of Crossfit training.
