This is brilliant. To think, I got it on YouTube for free! Here I am, practically unable to feed my family due to pricey yoga classes, when this has been out there all along. I'm a horrible, selfish person. So I gave this a shot but all I could track down was a yellow highlighter. Unfortunately, my abs don't look as defined as much as they look like I've got hepatitas. Or stupidity. (Incidentally, there are strains of either one are incurable.)
Please make special notes of what is said at :23 and 1:33. Priceless. Kids, I'm telling you, it doesn't get better than this.
