Met Coach at 5am this morning.  Knew I was going to get frustrated with the Squat Snatches.  I was right.  I just can't drop down into the overhead squat position.  Back, Shoulders or both something is hindering this action.  I dropped as deep as I could each rep still frustrated.  As usual wallball was solid.
