I found this fantastic, butt-burner on fitnessmagazine.com and have since shared with two friends, who agree it's a calorie-burning success. In just 20 minutes, you can burn 150 calories while WALKING (crazy, right?). I usually don't opt for workouts that have walking, but for someone who isn't a runner, I thought I would try it out...and I like it! For the first 5 minutes you start out at a speed of 4 at a 3-3.5 incline; follow the chart below and adjust the incline to best fit your level. Beginners should start with a speed of 3 or 3.5 mph; advanced treadmill users can go up to 5.
| Minutes | Speed (mph) | Incline (%) | |
| 0:00-5:00 | 4 | 3-3.5 | |
| 5:00-7:00 | 4 | 8-10 | |
| 7:00-8:00 | 4 | 4-6 | |
| 8:00-10:00 | 4 | 10 | |
| 10:00-11:00 | 4 | 5-7 | |
| 11:00-13:00 | 4 | 12 | |
| 13:00-14:00 | 4 | 10 | |
| 14:00-15:00 | 4 | 12 | |
| 15:00-20:00 | 4 | 2-4 |
