I have been PBing for over an hour
Honey, our bands can be fickle, you know that (granted you now have kick ass restriction!). You could just be tighter today. Some believe dehydration can make our bands tighter. I can't tell you why you had the PB tonight, but I hope you are feeling better! Just take it easy for the rest of the night and tomorrow! I'm sure it was just a fluke!
