Elliptical machines target the lower-body muscles, specifically working the quads and hamstrings. This exercise provides more quad engagement than walking, working out on a treadmill or spinning on a stationary bike, according to Ben Greenfield of Champions Sports Medicine.
Set the timer for five to 10 minutes if you've never used an elliptical. Increase the time by five minutes per week, gradually building up to 30 minutes, which burns approximately 300 calories. As your fitness level increases, you can work up to 45 minutes or an hour if you choose. Alternate pedaling forward and backward every five to 10 minutes to work different muscle groups.
