Some other details:  I’m 33 years old and while I pitched until I was 20 (2 years in college) I haven’t moved much since then.  Started Crossfit 7 months ago.  I have bad posture….slumped forward my whole life but have been trying to correct it the past couple weeks.  It will take serious time, bad habit.  Also I  sit in front of a computer all day and my posture there is poor as well, working on it as well.
