Full Definition
The posterior chain in golf: Gluteus Maximus (hip extension, external rotation), Hamstrings (knee flexion and hip extension under load), Erector Spinae (maintain spine angle), Latissimus Dorsi (connect upper and lower body and maintain lag), and Rhomboids and Trapezius (shoulder blade stability). Loading the posterior chain is the essence of a correct backswing: the trail hip internal rotation stretches the glute, hamstring, and lat simultaneously, storing elastic energy. The release of this energy drives the downswing. Golfers who lack posterior chain loading use arm muscles to compensate. GOATY Step 1 drill specifically loads the posterior chain.

Frequently Asked Questions
What is Posterior Chain in golf?
The group of muscles running along the back of the body — glutes, hamstrings, lats — that are the primary power source in the golf swing.
