Ok so first I own every DVD workout Cathe has put out - and am a Cathe fanatic. That said, I found myself recently with a very painful foot problem - almost could not walk on it - much less workout as usual. My doctor did blood, xrays, and could not find anything wrong in the tests. I spent a week on Rx pain killers and resting. Then I rode exercise bikes - got bored shortly! Then to make a long story short I was looking for a cardio workout I could do which would also strengthen my feet. I happened onto Barrett's "Barefoot Cardio" DVD and I am SO glad I did. It is fantastic. Low impact, of course, and works the whole body. I was skeptical, but it does actually get my heart rate up. Not into KPC range, but into moderate cardio range. It is gentle on all joints and manages to work/stretch not just feet but my problematic shoulders, knees and back as well! Also there is just this feeling of joy and stress-reduction throughout. I feel really healthy and totally flexible after doing it. It's a keeper and I know I will keep doing it long after this foot problem resolves. If anyone ends up seeing it, check out the look on crew member Michelle's face towards the end - I have been doing video workouts since 1985 and I don't think I have EVER seen such a look of pure joy and delight in movement, on one of the crew's faces. And eventually, after my foot is really recovered, I will get back to my KPC and my new shock cardio DVDs.
