I ask because I have thought about this!! Of course, my idea is better than theirs (ha!). I would actually have an HP or Dell treadmill (patent pending!) with the dashboard an actual keyboard with a monitor to surf, email, whatever.... work while you work... your ass off, that is!
Read the link to the article. One man lost 16 lbs in two months by passively walking on his treadmill while he worked.
Now, if you're like me, you're not good at multi-tasking when it comes to physical activity. One of my very first blog posts to this site was about my treadmill injury... yes, you read that right. I sustained a pretty substantial injury from walking at a warmup pace on my treadmill. I flew right off the back of the damned thing... and now I'm considering walking AND emailing/posting/blogging? Either I have come a LONG WAY, baby... or I'm totally nuts (maybe alittle bit of both).
Anyways, I am going to give it a try. Tomorrow. Promise...
