I often see golfers have a movement in their swing that it kind of slips over the course of maybe a season or even half a season. And I see how much rotation they have in their back swing, so they setup to the golf ball in the right place and they can see all of this, and they can check all of this in the mirror as well, make sure it’s all the same and that’s all good. Then during the back swing they know they should rotate so they start to turn back but then it’s difficult sometimes to decide when to stop. We are always told that we shouldn’t go too long; we shouldn’t go beyond the three o’clock line. But how can we confirm that we are getting enough shoulder rotation in the back swing? Here is a great tip for you, as you are turning into your back swing you’ll notice your front shoulder for me it’s my left shoulder. Your front shoulder starts to come around and underneath your chin and when it’s underneath my chin there I know it’s in the right place I’m looking directly over my chin over my shoulder down on to the golf ball. And that’s great confirmation that I have actually achieved the desired 90 degrees. If I never get my shoulder quite underneath my chin I’m looking to the side of my shoulder here, I have probably haven’t rotated enough and if I get my shoulder under my chin and then carry on some more there is a fair chance I have over rotated beyond the 90 degrees. So the little shoulder under the chin checkpoint is a great way of ensuring you’ve got a 90 degree shoulder rotation ready to start your back swing – sorry ready to start your down swing. So 90 degrees shoulder turn then I can start coming down, now it’s quite important to make sure the shoulder goes under the chin and not into the chin. Anytime your shoulder lifts up and hits your chin there is a fair chance you’ve lost you’re posture, you’ve lost your spine angle and from this angle it should look like this, it shouldn’t look like this. Here the shoulder has moved upwards into the chin, I have lost my spine angle, I would have to went deep back down to hit the golf ball. So shoulder under the chin 90 degree checkpoint, turn back through. Its well worth checking that every couple of weeks just to make sure you’re still maintaining the correct amount of shoulder rotation throughout your golfing season.
