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.

A faster pace will provide you with a more challenging workout, both to increase your endurance and improve your cardiovascular health.
