I have been doing interval training on the treadmill, doing about 4-5 miles each time. However, I am getting a little bored and want to mix it up a bit. I read on another website that if you set the incline as high as it will go (my treadmill is 10%) and walk at a pace that you can keep up with (but not too slow) you will burn mega calories.
Has anyone done this? Any other suggestions?
