Younger and Stronger - using 1/6 formula

Looked back at book Younger Next Year by Chris Crowley and Henry S. Lodge and learned more from a second reading. Seems like you create some inflammation in your body when you exercise vigorously. The authors explain that the slight pain you inflict on your body, down to the cellular level, creates growth and creates greater strength and health in the long run. They promote the use of heart monitors to keep good track of your pulse. In general terms, the maximum pulse rate can be derived by using the number 220 and deducting your age. In my case, the age is 63 years-- so my max heart rate would be approximately 157 beats per minute. You then strive in your exercise regime to get to 65% of your heart rate, or higher with more rigorous workouts. You might even move beyond aerobics to anaerobic levels-- with rates close to 100% of your max, maintained for a minute or two-- with sprinting 100 yards or some other relatively extreme behavior, for a senior person that is. The overall result is that you start feeling better and your body maintains itself at a more youthful level from the age of 60-85 years. It's kind of a natural preservative-- like dipping yourself in citric acid to reduce your physical detoriation with an exercise habit of one hour a day for six days a week. I think of the formula as 1/6-- one hour per day/six days a week.

So far this book has been a good influence in my life. I have been combining gym workouts for strength, about 2 per week, with 3-4 days walking the hills adjacent to my neighborhood in Austin. There is a bit of cultism or self-absorption perhaps in the authors' fondness for their system-- but I am falling into line with many of their assertions. I have not bought the heart monitor, a strap that goes around your chest and signals your pulse rates to the wrist monitor you wear like a watch during the workouts. I have noticed pulse rates on the elliptical machine and other apparatus at the gym and sure enough when I hit about 120 bpm (beats per minute)-- a line of sweat forms at my brow and telltale moisture appears at the neckline of my shirt.
