How to make
a perfect
backswing
every time:

Keep your left
arm in tight
It's easy to talk about
making a shorter
backswing, but since
you're looking at the ball
and not behind you when
you swing, it's difficult to
know how much shorter
you should swing the club.
Here's how to know:
As you take the club away,
keep your left bicep in
contact with the left
side of your chest.
Maintain this
connection and your
backswing will reach its
natural end point without
you having to think about
it. Keeping your left arm
tight against your chest
prevents you from lifting
or raising your arms, and
allows your right shoulder
to stop turning at the right
moment in your swing.

Don't worry about it!
If you think you need a long
backswing to hit the ball far, that's just
not the case. You'll hit the ball farther
more consistently if you make contact
in the sweet spot, even with a slower
or shorter swing. The left-arm trick
makes it easy to swing your club on
plane both back and through. Your
contact will be better and you'll see
the benefit in extra yards.
