While you have to watch videos or take classes to learn some workouts, there's one exercise almost anyone can easily do. In fact, researchers have found walking just a couple of miles a day can guard against both heart disease and cancer. And the health benefits don't stop there. In one recent study, people over age 60 were assigned either brisk walking, or less strenuous stretching exercises. After six months, the walkers showed greater improvement in thinking and memory.
Researchers think that's because walking helps boost the amount of oxygen reaching the brain.
But before you lace up your shoes and hit the road, there are some things to keep in mind. Recently, I spoke with Doctor James Rippe, a leading expert on walking. And I don't think you need to learn any particular technique. Most people dramatically underestimate simple walking in terms of its cardiovascular benefits. So the message is, take something very simple, but do it.
