I built a treadmill desk a few years ago and I love it. It's tough to get myself out of my chair to use it, but once I get started I like it.

It's definitely not an all day solution though. I usually start feeling tired after about 45 minutes. I start sweating at about 1 hour. After 1.5 hours, I need a break. So I go back the my sit down desk.

The basic idea is to avoid staying in one place for a long time. Treadmill for an hour or so, then site for a while. Repeat.

How fast are you going? I had mine set on 1-2 mph, and never broke a sweat.

Regardless, I am a big fan of breaks; if I'm out hiking I'll also stop every couple of hours to sit down for a bit. And really, when I'm sitting I try to stand up and move around every couple of hours.
