What does a flat shoulder plane indicate during a golf swing?

A flat shoulder plane during a golf swing indicates that the shoulders are turning on a more horizontal plane relative to the ground. This characteristic is crucial to maintaining an efficient swing path, as a flat shoulder turn can facilitate a more effective coil of the upper body. When the shoulders rotate in this manner, it allows for the arms to maintain proper positioning, which can lead to a better strike on the ball.

In a flat shoulder plane, the player typically positions the club more on plane, which helps control the direction and trajectory of the shot. This position can also minimize the risk of overswinging or hitting from an incorrect angle, contributing to a more consistent and powerful swing. Understanding this concept helps golfers analyze their own swing mechanics and make necessary adjustments to achieve optimal performance on the course.
