One of the great benefits of elliptical trainers is that it provides an aerobic workout through a weight bearing exercise. Running does this, of course, but working out on an elliptical trainer provides an impact to your joints comparable to walking. In addition, many people report that working out on an elliptical trainer feels like less work than working out on a treadmill. Plus, if you use the upper poles on the elliptical machine, you are working your upper body as well. With a treadmill, you get no upper body workout.

Serious Runners Take Note

But, what if you are training for a marathon? Here's where a treadmill has a real advantage over the elliptical. If you are training to be a runner, you need to run. The gliding motion of the elliptical machine won't provide you training comparable to running in terms of preparation for a race.

Impact Is Not All Bad

One final issue about elliptical trainers - the very thing that makes them great also has its own disadvantage. Elliptical trainers are so popular because they provide a low impact workout.

So, if your knees are healthy enough to withstand the impact, running will protect your bone health in the long run.

The most important issue when it comes to any exercise is longevity. You need to find an exercise that you can stick with. If you have joint or knee problems, an elliptical trainer can allow you to workout more easily than other weight bearing exercises. But, if you love to run, and are healthy enough to do so, the elliptical trainer might not be for you. It is beneficial to try out both machines, and, if you're buying a machine, be sure to check out elliptical trainer reviews as well as those on treadmills. Be assured that both can help you improve your cardiovascular health, lose weight, and gain overall fitness.
