Posterior Chain Engagement

Posterior Chain Engagement is a critical part of Crossfit; it focuses on the engagement of the group of muscles, tendons, and ligaments on the posterior (back) of the body, including the hamstrings (biceps femoris, semitendinosus, semimembranosus), gluteal muscles (“glutes”), and spinal erectors.  the Posterior Chain is ultimately the powerhouse of the human body with the gluteal muscles being the engine.

You’ll notice that the 9 foundational movements require Posterior Chain Engagement either as a source of power generation or for stability and injury protection. Thus Posterior Chain Engagement enables core to extremity, functional movements. Its therefore the goal of a good coach to ensure that the athlete can maintain and develop this Posterior Chain Engagement regardless of  work capacity though the use of threshold training.

Posterior Chain Engagement is ultimately developed though functional movements such as the deadlift, and pull ups, but assistance movements should also be used to help strengthen and ensure that there’s sufficent stability around affected joints.
