BOISE -- Some people walk to and from work. Some people walk to lunch while at work. And some people, well, walking is their job. Mailmen, dog walkers, and professional golfers may come to mind.

But there are also those who try to do two things at once working while getting in a week's worth of exercise.

EOI Direct in Boise looks like your typical small office work space.

"It's the only office I've ever worked in," said Allison Berger, who has worked at EOI for eight years. "So is it a typical office?"

Well, if that judgment is based what Berger is doing, sitting at her desk answering phone calls and emails...then, yes.

But a few steps away from her desk, Kirk Smith steps to his. As the director of operations, Smith has spent the last six years working while walking on a treadmill.

"Yeah, every day," confirmed Smith.

He's logged mile after mile, step by step. Enough to make a daily walk to Caldwell.

"Yeah, what is Caldwell a little over 20?" asked Smith. When told it's about 27 miles he adds, "Uh, maybe I've been going a little under."

Some may see this way to work as a bit distracting. Not Smith. He can even chew gum.

"I do," he laughed.

Smith still opens mail, answers emails, and carries on phone conversations. He just does it at three-and-a-half miles an hour.

"A lot of the things that you do in an office environment is exactly what I'm doing," said Smith.

When asked to describe his job, Smith can go on at length.

"When you live in a condominium association you don't actually own the outside walls, so when you refinance a loan or you have a loan with a lender..."

So you can understand why he need to put some sort of stimulation in his workday.

"Yeah, that's a fair statement," he agreed. "No question."

Two years ago Smith tried to break a world record on his TrekDesk for walking while working but lost to a pipeline worker somewhere in the Northeast.

"It was a three-month push and I averaged 27 miles each day over those three months," remembered Smith.

His commitment started because he was tired of being too tired to work out when he got home from work.

"This is a way that I can build it into a lifestyle and take care of a lot of things without having to think about it," said Smith.

So over the years how many miles has he clocked on the clock?

"You know, I used to count," admitted Smith. "I don't anymore."

Let's just say he's lasted longer than a couple of his treadmills and plans on lasting even longer.

"I hope I can do this the rest of my life."

How does Smith get to work, by the way? He drives the six miles because to do otherwise would be just crazy.

EOI Direct employs 12 people and each have access to a TrekDesk treadmill but most only use it a couple of hours each day.
