Is that on the DVD in the green box? It says 'Level I For Health' on it, right?

I just watched it for the first time last night and I don't remember hearing him say to do "reverse breathing". I heard him say to keep the tongue on the roof of the mouth, it looked like he was breathing in and out through his nose, and he said to move the stomach in and out slightly while breathing. He also said to try to use the whole body to breathe.

Do you remember approximately where (how many minutes in) on the DVD he said that?
