Get Fit Challenge 5: A Reader's Treadmill Workout

I really enjoy walking or running outdoors, but it's been way too cold here in VA for outdoor workouts so I've been a gym rat for the past few months. Here's one of my recent treadmill workouts. I like it because it switches from walking to running and also changes inclines, keeps your mind busy, and goes by faster than if you were doing the same pace for 40 minutes. 

Enjoy!
