#676 The Foundation of Power: The Science of Stance Flare, Knee Stability, and Ground Pressure (Part 7)
A powerful golf swing starts before the club moves. In Part 7 of our Golf Biomechanics series, we examine how stance, foot flare, knee stability, and ground pressure create the foundation for speed, consistency, and efficient movement.
Foot flare is not simply a setup preference—it determines how freely the hips can rotate. Current research suggests 10–20° of trail-foot flare and 20–45° of lead-foot flare. The trail foot supports a deeper backswing, while the lead foot allows the pelvis to rotate freely during the downswing. Proper foot flare reduces stress on the knees and lower back while…
