Elliptical machines: What are the fitness benefits?

Thirty minutes of moderately intense exercise on most days of the week can increase your cardiovascular health, lower your blood pressure, help you maintain a healthy weight, and build stronger bones and muscles. Elliptical machines are a great way to get your 30 minutes. These machines combine the natural, fluid motion of walking and cross-country skiing to provide a low-impact workout. Elliptical machines are less stressful on your knees, hips and back than is running. Some machines also have poles, similar to ski poles, attached to the front, so you can exercise both your arms and legs. Plus, most can be pedaled in reverse to work different muscles. You'll get the most effective workout if you maintain good posture: Keep your shoulders back, head up and abdominals tight. Let your lower body support your weight.
