There are as many variations of it as there are exercise gurus. First you calculate your maximum heart rate. I use the Tanaka formula, 208 – (0.7 x age).

Well maybe. My Optometrist says macular degeneration is more likely to occur in those who over do it -- think marathons -- rather than 30 minute work-outs.
