Since you can get an effective aerobic workout out of both the treadmill and the elliptical machine, the best answer is to let your specific goals determine your choice.
However, elliptical machines may have a slight edge over treadmills:
-Unlike treadmills, most elliptical trainers include adjustable handles that, like ski poles, allow you to exercise your arms as well.
-Elliptical machines are not as hard on your back, knees and hips, although both demand roughly the same physical effort.
-Most elliptical machines allow you to pedal backward as well as forward, which means some muscles in your calves and thighs will get a better workout than the other way around.
Like we mentioned earlier, the use of an elliptical machine is considered a low-impact activity, a good alternative to elining. If used correctly, it shouldn’t cause knee pain, although those with an underlying knee condition, such as arthritis, could experience pain. If this is your case, a stationary bicycle may be a better option. Ask your doctor which machine is the right one for you.
And what if I’m training for a 5K race, or even a marathon? In this case, and only in this case, the treadmill is better suited than the elliptical machine. Even when running is your physical activity of choice, combining workouts on the elliptical trainer with other low-impact machines will help to keep things interesting and prevent muscle overuse.
If you’re using the elliptical trainer, remember to always keep a proper posture to make sure your workout is as effective as possible. Maintain your shoulders back; keep your head up and your abdominal muscles tight. Looking forward will help you achieve the right posture: let the lower half of your body support your weight.
