Hello, this is David Cho here
Almost all golfers have Two planes in their golf swing
The problem is
many golfers think there is only one plane
and think they do 'One Plane golf swing'
This confusion causes a lot of problems
I will explain what One plane swing is first
At the set up posture, we can feel the swing plane
which is made by your shoulers rotating
around your spine
In this swing plane, your shoulders and arms
rotate together
That is One plane golf swing
Therefore, to do One plane golf swing
you need to bend your upper body more
so that the swing plane is steep enough
However, the problem is most golfers have
a golf set up posture for Two plane golf swing
Your upper body may not bent enough
to do One plane golf swing
So, the swing plane by your shoulders rotation is
too shallow for your arms
and your arms are relaxed and dropped down
then your arms (hands) are already outside of
your shoulders swing plane
So, there are two swing planes
Then what are the common mistakes
with this confusion
The fist one is your arms follow
your shoulders swing plane
which may make your swing too flat
, getting too much inside with your back swing
and turning wrists
and 'Open club face'
and complicated swing path
and narrow swing arc
The second problem is
Your shoulders may follow your arms swing plane
Then what is One plane swing?
In general, that is Recognizing only One swing plane
although there are two swing planes
feeling your shoulders and arms rotate together
in a plane
So, if you do One plane swing
you need to understand
your arms swing in a steeper plane
So, it is really good to do Two plane swing
as there are two swing planes anyway
If you have a key position,
it will help you for a Consistent golf swing
This is a common misunderstanding
about Two plane swing
Your shoulders and arms turn together at Takeaway
Then your arms go up
while your shouldes rotate
Initiating a golf swing with One plane swing concept
Then two plane swing to the backswing top
and the swing path is
shallow then steep
which is hard to be connected
Therefore, even if your key position is a bit further
please think the club head is not rotating
with your shoulders, but going up
in a different swing plane
Thanks for watching
