I had to do this recently and was reminded why I hardly ever bother: it does absolutely nothing for me. As in, I pull my leg right to my chest so it's touching my boobs and my knee touches my chin but I don't feel any stretch. I've always wondered why people bother. I mean, what is meant to be pulling? What is it meant to stretch? Where are you supposed to be feeling it? I'm not particularly flexible or inflexible before anyone says that.
Do you feel anything doing this (so-called) stretch? Could I possibly be performing it incorrectly? 😕
