The benefits of weight-bearing exercise without the impact.

Part treadmill, part stairmaster, and mimicking the pedal movement of an exercise bike, the elliptical trainer offers a unique combination of fitness benefits, without the impact on knees, back, hips or joints. This weight-bearing exercise allows you to burn calories more efficiently than non-weight-bearing workouts, plus effectively builds bone density.

More than just a lower-body exercise, arm handles combine with leg motion to provide a total body workout. In addition, the elliptical helps to create a lower "perceived rate of exertion" - you do more work and burn more calories while feeling like you're producing less effort.

This cross-training-style machine can also typically be programmed through electronic settings to meet your specific goals of calorie burning, speed and distance. One other unique advantage is that the elliptical can also be "pedaled" backwards in addition to forward, to effectively work a full range of leg muscles.

The elliptical has proven popular with those who are looking to receive the benefits of a full-body, weight-bearing workout, without the stress and pounding.
