I recently bought a workout DVD series. (I won't mention the name, because I think it's against the rules.) Anyway, it's a 25 minute video and it is KILLER! I have never worked out so hard in my life. Normally I am a walker, or I ride my stationary bike. The last year or so, I have seen no real benefits from either of these. This is my second week with this program, and I already see a small difference. I can already do so much more in the videos than I could last week. I am NOT a runner. When I run I feel and look like a floppy fish. But, I've known a lot of people who stay fit with a strong running regimen. Then again, one of the most physically fit people I know does a lot of landscaping around her home to stay fit. The differences in style leads to the the question: what is your favorite thing to do for exercise?
