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.
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 swing is an arc from an above and inside the ball view. The clubhead should travel along the target line for a few feet before it starts arcing back to the inside. Here is a drill to help achieve that.
