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.
Minute for minute, using an elliptical machine is likely to burn more calories than walking. According to recent estimates by the Mayo Clinic, a 160-pound person using an elliptical machine for an hour would burn 365 calories. The same person walking for an hour would burn 314 calories. (If that person used a stair-stepping machine, he or she would burn 657 calories, by the Mayo calculations.) The person on the elliptical machine also would put far less stress on his or her joints during the workout.
