When we sleep on our side or slouch all day our back muscles get over stretched and tight from being in that position. In this video, I show you a foam roll stretch that works the infraspinatus, teres minor, and latissumus dorsi muscles. It will be quite painful at first because of how tight these muscles are. Keep working on it and it will improve dramatically within a week or two. If this stretch helped you, be sure to check out my static back stretch to help improve posture.
