How Much Should You Exercise?

Physical fitness authorities seem to have fallen into the same trap as the nutrition authorities, recommending what they think may be achievable, rather than simply informing us what the science says and letting us make up our own mind.

Most of the content in my book How Not to Die came from my video research, but this video actually sprung from the book. I wanted to include exercise into my Daily Dozen list, but needed to do this research to see what was the best “serving size.”

I wish someone would start some kind of FitnessFacts.org website to review the exercise literature. I’ve got my brain full with the nutrition stuff (though there’s so much good stuff I don’t have time for that there could be 10 more sites just covering nutritional science!).
