The thoracic spine is in the upper back, and it goes from just below the neck to about mid-back. That’s where we get all our motion from, so that’s where you’re going to get the majority of your shoulder turn from. We’re going to see how much motion you have in that thoracic spine.
All you need is a chair and you’re going to sit on the corner of the chair. You can put two golf clubs or alignment rods to make a 90-degree angle on the floor and that’s going to give you two 45 degrees. We’re going to sit right in the corner with our feet right in front, keep our knees together, take a club, put it behind your back, sit nice and tall, and try and turn your shoulders. When you turn your shoulders, you want to be able to see that club go past that marker on the bottom which means I can move more than 45 degrees to the left. Do the same thing on the right side. If you can go more than 45 degrees without really struggling, then you probably have a good thoracic turn.
