I said I’m ready, now what?

Stretching..

So i joined the roller derby team, and one of the stretches we do as part of our warm up and cool down is called the "porn star stretch" Yeah.. I kid you not. I was like what the freak. did i somehow end up somewhere else..I thought i came here to skate. Being the fitness fanatic that i am,  I proceeded to inquire what muscles we were supposed to be stretching? fair question right?  the girl who was leading the stretches responded with, "it stretches the quads, and inner thighs" i don’t thinkt that she knew what she was talking about so i thought I’d ask here if anybody knew if laying doggystyle was an actual stretch…. ( did i just say that) I’m not trying to be nasty but I’m curious to see if this "porn start stretch" is in fact an actual stretch and what muscles does it actually stretch.

Please do not respond with vulgarities..  And if you have any suggestions on stretches for a warm up or cool down for roller blading they will be very welcomed..thanks.
