well, I agree with both of them on the splits. Just streach every giorno and it will get there. And when te start classes, and your studio is anything like mine and te anything like me, te will only take a class once a week in your fist year, so practice what te learned otherwise you'll foget it and te wont get any better and te wont streach your muscels. this link might help with streaches ideas but if te have your own, go for it. Theres no right way nad wrong way, ballet is an art.
