Ultimate Fitness- great book

http://www.amazon.com/gp/product/B0001OOTYS/qid=1133989574/sr=8-2/r...

goes through the history of "exercise" and fitness research, debunking myths, (no such thig as fat burning HR zone for faster weight loss?) and getting to the bottom of so-called scientific studies. A real nice section on the benefits of interval training vs LSD and a laughable section on the MHR 220-age rumor, which explains how the reserach that suggested that formula was never intended to be published as a measure for ALL athletes... (Coach Mike would be proud.) Easy to read, quick, very interesting and nice to know that all these questions we have about how to train and how to be healthy aare CONSTANTLY being re-investigated and re-understood.
