I'm getting a little bit unnerved about it actually, beacuse up till now, every stretch has just been completely painless, as in no pain at all, could'nt feel the difference at all. But now, this one is actually pinching and feeling a little tender. I wouldn't call it actual pain at all, but it is a little uncomfortable and I haven't tried that before

What are your experiences?
Which did you find the hardest and how did you go about getting through that stretch?
