I've been taking a swimming course through my local community college & they are all about swimming faster without regard to swimming efficiently. She wasn't even sure what T.I. was.

I've dropped the course because I don't want to practice my bad habits. I do the T.I. drills and they really help a non-swimmer like me. It can get tedious, especially when I have a bad day in the pool (just can't get the feel right) but I do think it works.

Does anybody have the DVD? If so, is it good? I've read the book, but I'd like to see it in action.
