Many people struggle with faulty posture (forward head and rounded shoulders).  Tightness in the pec major or pec minor can negatively affect the body.  Often, the throwers I see suffer from tightness in this region.  Any overhead athlete can be affected as well as the person who sits and types all day long in the office.
The video below reveals how to use a trigger point ball and block to work on soft tissue tightness.  I like the TP ball and baller block from Trigger Point for this exercise sequence. 
For more information on this technique and its application, click here to read my online column for PFP magazine. Note: the final “W” motion in the video is not described in the column article, but it is another option that can be included.
