There are a thousand and one ways to work out on a treadmill, but my favorite is intervals. Changing your pace every few minutes busts through the boredom often associated with indoor running, and once you set your pace on the treadmill it’s difficult to cheat. In this workout the set speed pushes you beyond my comfort zone with a gradual build, and the

minute recovery is just long enough to lower your heart rate to rev myself for the next interval. Another reason to love intervals: they help you lose belly fat . This workout combines running with walking, so if you new to intervals you should give it a try. Ready to check out the workout.
