Moving through pain

For my own experience of moving through pain I have found that the best way to decide whether or not it is safe for myself is how do I feel when I don't move.  When I'm not moving my body I'm hurting anyway so to stay mobile I continue to move.  Thats not to say that when it is an actual injury that I don't take a break but to evaluate my pain to see if it is something I can work through with or without modification.  Often when we are sore we take it as an excuse, a way out if you will.  Being sore is quite normal expecially when you haven't moved in that way or used that muscle for awhile.  If something genuinly hurts then there are ways to work around the pain instead of stopping the movement altogether.  In doing so it keeps you mobile.  My biggest peeve is when it becomes an excuse to stop all movement altogether because there are always ways to keep ROM in the rest of your body in that case.
