Today I'm gonna Show you the 90/90 test
This looks like John Wayne has told you to
"Stick em Up"
Three outcomes
1) You can rotate your arm past 90 degrees
2) You can rotate your arm to 90 degrees
3) You can't get to 90 degrees
We then test this in golf posture
If your elbow moves, (forward, back, up down)
you are cheating fella and you don't have the
rotation.
Causes of this can be
Shoulder Instability
Overdevelopment of the Internal Rotators (
Chest )
External Rotator Injury or Weakness ( Back)
It can cause the following in your golf swing
Loss of Posture,
lying Elbow,
Chicken Winging,
Early Extension
Get screened fella….
