Your thoracic spine is the middle segment of your back. Think of the area between your shoulder blades, this is where your thoracic spine lives. Proper extension mobility here is critical for proper mechanics of the shoulder. As we spend more and more time sitting at the computer, staring at our cell phones and having generally lame posture our thoracic spines become stiffer and stiffer. This stiffness can alter mechanics at the shoulder, over stress your neck and even limit optimal breathing during exercise. If sitting up straight is a struggle for you, there is most likely some t spine mobility work to be done.
In addition to regaining your thoracic spine mobility we like to add mobility work to the lat muscle as well. Commonly tight in the same folks that have stiff t spine mobility we want to ensure proper length at this muscle. It's not hard to get this mobility back. Check out of favorite mobilizations below.
