Foam roller for the splits

Just wanted to share this vid, which uses the foam roller to stretch for the oversplits:  http://www.youtube.com/watch?v=U-lEp0Xx1ko I can't quite get into the splits yet, but using these two stretches has improved my flexibility immensely.  In just a few days of adding these stretches to my usual flexibility routine, I've gone from about 5" away from the splits to 2".  And the second stretch on the roller especially feels good!
