Try walking (Score 1)

I lost 40 pounds through a combination of a low carb diet (no bread, potatos, rice, pasta or sweets) and walking about 4 miles each workday. To make the walking more interesting I listen to an iPod filled with audio books from Audible. I used to get this exercise by walking to work, but now I live close to my workplace, so I take an hour off for an afternoon constitutional.
