Thanks for answering my numerous questions, Sam. I've been carefully trying pulsing (i.e. relaxation and contraction whilst stretching) when I do my stretches, and I'm pleased to say that I can see a noticeable difference, especially in the time it takes to get my muscles ready to go down into my splits. Update: I just got my right splits. Yay! It's definitely not as good as my left, but its there.
