Should 15,000 Steps a Day Be Our New Exercise Target? – The New York Times

Very interesting research on postal service workers in Scotland, but already on the books.

My ongoing research confirms that brisk walking, while mixing in occasional intervals, and even 30 second run bursts yields greatest health benefits. However, it will be very difficult for most of us to sustain a 4 minute walking pace, for even an hour. A confounding variable here is that the postal workers are also carrying weight on their packs.

Wait! Isn’t this power walking, or heaven forbid, brisk backpacking?

Functional fitness may well demand dramatic lifestyle choices, like moving to the Maine woods and working the land, or living in a city and giving up a car and walking instead of using public transportation. I’m not kidding!
