Day 18
10,272 steps
I walked 2 1/2 miles (about 5,000 steps) to a Starbucks coffee shop
today. I read Hardwired for Fitness a book by scientists Robert Portman
and John Ivy. After reading for 30 minutes, I returned the 2 1/2
miles back home. Here is what I learned:
Why does walking work? Our DNA is hardwired for low-levels of sustained
activity. Our DNA has evolved since the days of our caveman ancestors to stay
on the move. Paleolithic man moved constantly as part of his survival. A
wounded animal hunted by our ancestors may have traveled for hours before
relenting and falling to the ground. The term "hunters and gatherers"
describes mankind's existence prior to the development of farming techniques.
Today we serve our bodies best by pursuing less intensity activity over
longer periods of time. The activity most easily sustained over an hour or more
per day is-- walking. If you incorporate brisk walking into your lifestyle your
health and strength will improve dramatically. The regular walker striving for
10,000 steps (about 5 miles per day) will enjoy greater benefits than a gym
enthusiast following a rigorous 30 minute workout for 3-4 times a week.
Improving your health and strength just by walking defies logic-- until
you try it. Get a pedometer and give it a try.
