Something that has been become obvious is that Grandma was right when she told us to sit up straight and that good posture counts! We see a lot of athletes come in exhibiting what is called Upper Cross Syndrome. People develop this through a variety of paths. Bad posture is a contributor, but so is computer use and vision issues. Another cause is over-development of the anterior chain and under-development of the posterior chain. In other words, working on the "beach" muscles as opposed to the "working" muscle.
Check out the following video for suggestions on how to remediate this problem through stretching and mobility work. We will continue to do foam roller and mobility work after WODs so that we can head this off in some of you and remediate in others!
