Time Commitment. A treadmill can help you lose weight and tone all areas of your body, as long as you spend enough time on it. Depending on how rigorous your workout is, plan to spend between one and a half and three hours a week walking, jogging, or running.

Using an incline on the treadmill not only works your calves, but it helps build other muscles, burn calories and improve cardiovascular health. Another benefit of treadmills is customizing an exercise routine that fits your needs. Adjust the incline, speed and even use the preset workouts to reach your fitness goals.
