Slight injury...

I think I pulled something in my left hamstring last nigth while squatting. I was doing my normal routine and feeling really, really good. I had hit 415 for 2 sets of 3 and it felt like the bar on my back. My next set I went to 495 for doubles, but on the first rep of the first set I felt something in my left hamstring. It is sore this morning almost like a charlie-horse or something. I will keep a close eye on it...
