We're going to dive into an unexamined part of the walking math.

Hi, I'm Dave. Welcome to Walking is Fitness, a daily 10-minute podcast designed to provide you with a little added motivation to get out the door and take the walk.

Today's 10-minute walk starts right after this.

It is a foggy morning in Myrtle Beach, South Carolina. In fact, the fog is getting thicker since I left the house. I'm walking along a trail which is probably three, maybe four-tenths

of a mile. And I can see from one end to the other, except not at the moment. When I started

walking down this trail, I could see from one end to the other.

And this is how I can tell the fog is getting thicker because I'm turning around now and walking back.

And I can't see the other end.

It is completely shrouded in fog.

It's actually kind of cool looking.

So some walking math that I have been talking about of late really concerns how much time we spent sitting each day.

Probably a better way to put it is how much time we spend sitting each day.

And stuff tailing on the research indicating that sitting, prolonged sitting is dangerous.

And this other aspect of the research, which is actually a little scary, how those who exercise maybe even 30 minutes

and then spend the rest of the day sitting, it's almost like that exercise never happened.

And so the math that I've been doing is let's take a look at the 24 hours we spend each day.

We'll assume eight hours for sleeping, so now we're down to 16 hours.

If you walk 20,000 steps, and most people, whether you walk or not, would say the 20,000 steps is a lot,

and you gotta be super healthy.

If you're walking 20,000 steps a day,

that's like super healthy stuff.

It takes about four hours a day to walk 20,000 steps.
