Do you want to burn loads of calories but don't have much time? Well, here is a solution for you...try treadmill walking or running up an incline. Going up hills burns calories at an incredible rate. For example, say you have a 160-pound man walking on a level treadmill at a leisurely pace of 2.5 miles per hour, which uses 4 calories per minute. That balloons to nearly 7 calories per minute when walking at the same speed up to a 10 percent grade and a whooping 10 calories per minute when walking up a 20 percent grade. Walking up small inclines increases the energy cost between 75 and 250 percent. Just as with any exercise, always start off conservatively and increase the incline and treadmill speed gradually. Increasing the grade on the treadmill- the world's most popular cardio machine- will help you melt the fat away while building nicely muscled legs. You have nothing to lose...so get on that treadmill and watch your body change. :)
