One of the best ways to improve rotation in the golf swing is to actually stretch those muscles used during the swing. A great way to do that is to use the Golf Stretching Pole. I’ve been using this device since 2005 and it’s a great way to simulate the turn you make in your shoulders during the golf swing. It’s also important to stretch on both sides – not just the side you take your backswing on.
Stretching your t-spine is also super important to improving the rotation in your swing. If you work at a desk or computer all day, there’s a good chance you’re hunched over for a majority of each day. This means it’s that much more important to open up and stretch your upper back and the areas between your shoulder blades.
The golf stretching pole is probably one of the best ways to go about improving your rotation.
