Physical activity including running everyday is essential to lose weight. A treadmill can be a great tool for burning fat. Exercising at a constant pace or sustaining the intensity for the workout duration is enormously effective for losing weight on a treadmill. A random workout involves a course of varying inclines and speeds. This creates an element of surprise all along your treadmill workout. With that said, it builds muscle as effectively as an outdoor trail run or a jog. Aerobic interval workouts on a treadmill involve alternating stints of rather low intensity aerobic exercise with short breaks or walks.
