I have shoulder issues, there, I said it. I’ve had surgery on my right shoulder and I’m not even thinking about touching my left (the right one scared me out of it). I do my physical therapy exercises, when I think about it (i.e. when the start bothering me) and I know I should do better. The CrossFit gym I just joined posted this rad video about loosening up your shoulders and I jumped all over it.
I went out and bought (2) 5 foot 3/4 inch PVC pipes for $5.14 and I’ve been in HEAVEN ever since.
Keeping mobile is very important if you’re susceptible to stiffness or impingement. We gotta give our shoulder much more love!

I completely understand. I work at the post office and the labor is no joke. My joints will never be the same again.
Also I recommend doing some kettle bell training. A 16kg will do wonders for your body.
I enjoy a good kettle bell workout. I don’t go over 30lb for overhead work.
