Whether you believe humans were born to move along upright or to crawl on all fours, we know at this point in our development that walking is one of the most natural exercises we can do.

Yet all to few of us, especially in the West, where the car tamed the land, are using this natural capability to its fullest advantage.

If you want to begin exercising, or add a nice bit of spice to an existing program, try walking for these reasons:

(1) Its inherently non-competitive. Unless you speed-walk, you can take your time, setting a thoroughly natural or challenging pace, as you please.

(2) Its portable, and even if youre staying in a concrete jungle, as I have on many business trips, a shopping mall will probably not be far away, and the hotel lot may actually be perfect, even providing a modicum of surveillance and security.

(3) Youll never have to wait in line! Unlike those trendy machines at gyms, your feet and shoes are always ready when you are.

(4) The endorphins, those happy-attitudes swimmers in your brain, will still tickle your fancy if you take a leisurely stroll or you speed up the clip.

(5) Youll be able to think and generate new ideas, and if youre like me, passively problem-solve at the same time.

Above all, its truly easy.

So, start today, and I know youll please yourself!
