As most of my students know, I focus on swing plane because having the correct shape to your swing means better ball flight and contact. Besides good posture, having good takeaway makes it easier to swing on plane. The takeaway position is like the first step in an instruction manual when putting something together. It is hard to build something if you skip or do the first step incorrectly. Therefore, I was my students to learn to perfect baseline plane ( when the club is parallel to the ground it is also parallel to the target line and along the toe line). The student can improve their takeaway with rehearsals, teaching aids, and waggles.
