The Titleist Performance Institute shows the chest stretch on a foam roller in the video below. This is particularly good for your chest and c-posture. Poor c-posture is when your shoulders are slumped forwards and you have excessive rounding of your thoracic spine (upper back) – both detrimental to your swing.
Make sure you have the correct posture for a more enjoyable playing experience. A swing assessment is a great way to identify opportunities for us to improve your game.
