>General Running>Treadmill "hills"
When you're on your deathbed, you won't be wishing that you'd spent more time at the office. But you will be wishing that you'd spent more time running. Because if you had, you wouldn't be on your deathbed.
"...and if you think walking 4MPH (15 minute pace) at 15% is easy, try it sometime for just 5 minutes"
Gotta agree with you there. Brisk incline walking is a surprisingly effective workout on the treadmill, and it's great if you don't want to pound too much. Our treadmill is currently upstairs (but moving down soon), and it sounds thunderous when I run on it; when I walk, I get no complaints.
