Kicking It Up a Notch

Given: a nice, level, paved surface neatly marked off in tenths of a mile, perfect for exercise and interval training (jog a tenth, walk a tenth, repeat).

Question: What's the difference between a hard, fast walk and a gentle jog?

Answers: The walk might well be faster. And can last longer. But the jog produces an impressive asthmatic wheeze in short order followed by sore knees later and a stiff body the next morning.

More answers: I now understand why the Wii Fit categorizes walking as "moderate" exercise (1:1 minutes exercised to fit credits earned) and jogging as "hard" exercise (1:2 minutes exercised to fit credits earned).

I also know that electronically exercised minutes (on a treadmill, elliptical, rebounder, etc.) are not the same as actually propelling your body forward in the way of foot meeting pavement.
