I just noticed my left shoulder is smaller compared to my right. Oh, man! And to think that I normally do a rep or two more with my left side. Will definitely have to correct this as it's quite visible the difference in size.

I do agree that I'm one of those who hardly ever stretches, I make it a point to do it whenever it's Legs day. I used to have massive DOMs but it's gone down considerably now that I stretch.
