Another setback. . .

I seem to constantly tweak my neck.  I had been dealing with a tweak on the left side, finally got past that, and now I've somehow done it to the right side.  I couldn't press yesterday, and pull ups have been out of the question for a couple of days now.   Frustrating.  

I guess one of the significant hurdles to accomplishing my goal will be to manage injuries.  They are inevitable, particularly at my age (45).
