Want to cover two topics here.  The first topic is Swing Direction.  Here is the YouTube Video.  In the above video I placed an alignment on the ball line a driver distance behind and in front matching the shaft plane.  The goal is to give you the ability to get the club to travel from under the one behind and over the one in front, over the one behind and under in front, or under and under.  With this you can get feedback where the club is coming from and going to.  Below I am showing a swing direction that could go under and over.
Now let’s chat about swing direction and attack angle. Â As a golfer it is hard to have a swing that is going out to in to and an upward attack angle so as we get the swing more from under to over there is a better chance. Â Here is another drill to keep the swing coming from the inside and now get the attack angle under control. Â I placed an alignment rod on the target line at an angle that put it a grip above the ball and rolled up a towel and placed that a foot in front off the ball.
This will set up a path that the club can come from inside low and go above the ball.  See the below images showing this movement.  I hit some balls with this setup and it got the path right 6-8* and attack up 3-5*.  Great way to maximize your driver for the most distance.  With solid strikes it will produce a high launching low spinning ball.  Click Here for the YouTube video.
Use these videos and drills to help get your swing shape where you want it and get that driver maximized.
