SWING STYLES PART 2 - 2 Plane Swings @planetruthgolf categories an upright swing as a 2 plane swing. A 2 plane swing relates to a higher left arm plane (for a right handed golfer) than shoulder plane. A two plane golfer naturally fights steepness in their swing due to the upright nature of their motion. On this basis there are some fundamentals that apply specifically to upright golf swings that would not apply to a more rounded swing. Check out @planetruthgolf for more on 1 and 2 plane swings.
