Great idea. Thanks! I will do that. I'm also going to sit in the squat position for at least a few minutes every evening to see if that helps too. Now that my overall workout is shorter, I'm going to stretch a lot more overall. I'm about as flexible as a railroad tie, so clearly I need to work on that.
Sorry for the thread jack, it just burst out of me when I saw that picture. To get things back on topic, it seems to me whatever feels right is the way to hold the bar. I know for me there's a pocket, or groove as someone mentioned right along the top of my back and shoulders. I sit the bar there.
