I saw an infomercial on Greer Childers and her breathing techniques for exercise. She basically says that we don't receive enough oxygen in our cells. And, that sounded familiar. Anyone try her program? Does it make you feel better, worse? How bout the toning exercises? From what I understand you can do all of them while sitting down and they are gentle. I just hate to invest more money on something that won't do any good. Any who are interested you can do a search with her name for information.
