Golf Swing Left Arm. Just the visual of it will put your mind in an un-dynamic position. The left arm has an equally important role to perform in the golf swing, perhaps even more so in that it directly controls the club face through impact.
Remember, whatever angle your left arm hangs – loosely – just maintain it during the backstroke and let it come out by itself in the downstroke. That's because a straight left arm creates width at the top of the swing, which helps golfers create more speed and consistency. Swing your left arm across your chest on the backswing and keep it connected to your chest on the way down.
Keeping your left arm straight during the swing requires the proper grip, arm swing, downswing path and body turn.
The radius of this circle, back and through to the finish, is defined by your left arm position (for a right-handed golfer).
Having a ideal golf swing is often a prime attribute of all of the leading players in the sport. The Left Arm Downswing Drill (LADD) is also covered in two phases, both without a golf club and with a golf club, allowing you to master these impact. Watch any elite player and notice how effortlessly they swing the club.
