We're going to take an iconic walk today. Welcome to Walking is Fitness. This is a podcast of action, providing a little extra motivation to help you keep that fitness promise you made to yourself.

Hi, I'm Dave. I've been walking for fitness since 2013, averaging about 21,000 steps a day.

I'm walking right now and would love to have you join me for the next 10 minutes.

I challenge you to count how many times you're going to hear the word iconic over the next seven days. That's because I am in Washington, D.C.,

and I'm going to take you along with me.

This is one of the most walking-friendly cities on the planet.

If you love walking and you love history, this is the place.

Today I'm on First Avenue, First Avenue or First Street,

First Street, Northeast. To my right is the United States Capitol. To my left, the Supreme Court, and the Library of Congress.

Of course, the U.S. Capitol is one of the most iconic buildings.

They started building this thing in 1800.

Now, one of the most recognizable features of the U.S. Capitol is the dome, which was actually built almost seven decades after they started construction.

And there's something about the dome that I didn't know until recently.

I grew up in Maryland, lived an hour away from D.C., spent quite a bit of time here in Washington,

school field trips when I was a kid, as an adult parent, brought my

children here. And then even as my kids outgrew, hey, let's go to D.C. I came here on my own.

In fact, probably in the last five, ten years, have visited D.C. more than all the previous years of my life.

I just love this city. Love walking here. Love the history. Can't get enough of this.

But here's something that I just recently learned about the U.S. Capitol.

Beautiful white building, stone building.

The dome is not stone.

The dome of the U.S. Capitol is cast iron.
