That's really slow going on a treadmill then. A mile is about 120 calories depending on your weight. A decent jogging pace should be at least 3-4 miles per hour

That's really slow going on a treadmill then. A mile is about 120 calories depending on your weight. A decent jogging pace should be at least 3-4 miles per hour. So adding a bit of incline it shouldn't be hard to hit 400 calories in an hour on a treadmill. I get about 200 per 20 minutes on the elliptical with a fairly relaxed pace and low resistance.
