One of the places people struggle moving from the most is the in the thoracic spine (aka t-spine or the rib cage). This is the area of your spine between your neck and lower back that attaches to your ribs. This area encases your vital organs like the lungs and heart, and stomach and if it doesn’t move well it can affect breathing, and digestion, but I digress.
Can you arch your spine backward, round it forward and rotate it in each direction? If you can’t then certain movements, like the golf swing can become less accurate. There is a big relationship between poor trunk motion and poor swing paths. Check out this drill called All 4’s Trunk Rotation too help improve your thoracic spine and rib cage mobility! Try 2 sets of 5 in each direction and let me know what you think!
