The source provides an extensive overview of hip biomechanics in the golf swing, emphasizing that the hips are the central "engine" for generating power, maintaining balance, and ensuring consistent contact. It thoroughly details the anatomy, function, and kinematic sequence of hip movement across the entire swing, from setup through the follow-through, noting key rotational angles and speeds achieved by elite players. The episode also explains common swing faults resulting from poor hip action, such as sway and early extension, offering specific drills and exercises to improve hip mobility and strength for injury prevention and increased distance.
