Some great golfers such as Greg Norman, Ben Hogan, Lanny Wadkins, Billy Casper, Byron Nelson, Gary Player, Mark Calcavecchia and even myself have all demonstrated footwork such as today's world number one Scottie Scheffler does. Let's find out how and why.
Too many golfers and instructors wrongfully assume that once the ball is struck that is the end of things and nothing else really matters. Once you understand the club in its entirety is also the shaft and the grip and not just the clubhead- you are on your way to better.
We often hear about pulling the left (lead) hip out of the way on the downswing in an effort to rotate. The area above the hip is way more important as I will show in this video.
Connection- Power- Force...How do they all tie in? 
The drill one 430 path drill stops the right arm from straightening- allows the body to open and turn- and keeps the golfer pushing force into the ground through the feet and legs. It also sets up the drill three post impact that keeps pressuring the shaft to the finish.
The golf club only stays on the target line for a short amount of time. It does however need to enter and exit in a manner that will spit the ball out straight and eliminate curvature. Here is a visual to how it works.
