If you want the best in elliptical trainers, it's no secret: you want a Precor. The company turned out the first of these novel exercise machines in 1995 and continues to be on the cutting edge of elliptical technology. With the EFX 546, you benefit from the patented CrossRamp technology that lets you set the angle of the equipment, in addition to the resistance, thus targeting a wide-range of muscle groups. Precors were also the first machines to let you stride forwards or backwards while you sweat, delivering a smooth, non-impact, and joint friendly ride in either direction. In fact, there are 20 different incline levels to choose from along with 20 resistance levels. All this adds up to a lower level of perceived exertion (RPE), so you won't feel like you worked out as hard as you actually did; 30 minutes on the EFX 546 feels like 15. The Precor EFX 546 is one of the most popular workout pieces with regular gym-goers; it received a 4.5 out of 5 stars from epinions.com, for instance. That's probably because the EFX 546 is a sturdy, built-to-last, commercial grade machine, that is equipped with a highly efficient drive system that requires little maintenance. Also, you can work on your range-of-motion and muscle strengthening, along with cardiovascular endurance, on the EFX 546. Grab some dumbbells and let go of the railings and your upper body gets into the act, too.

Elliptical trainers offer the benefit of a low-impact workout, while exercising both your upper and lower body. The elliptical is a cross between a treadmill and a cross country ski machine, but instead of your feet sliding back and forth like they would on skis, the pedals will move in an oval or elliptical pattern. Since your feet never leave the pedals, your feet don’t strike the ground so there is less stress and strain on your joints. It is like walking or running in midair.

With an elliptical trainer, you work your quadriceps, hamstrings, glutes, chest, back, triceps and biceps. The obvious benefit from exercising more muscles is that you tone more of your body. You end up burning more calories and fat in less time. Of course, to get the full benefit of the dual action workout, it is important that you distribute the resistance between your upper and lower body. Many people who exercise on an elliptical trainer place most of the resistance on their lower body and only go through the motions with the upper handlebars. To mount the machine from the side, grab the handle bar for balance and step on the pedals. The pedals have no resistance to your weight so be careful when climbing on and off. Once you have begun the pedal momentum, you simply keep pedaling while the elliptical trainer automatically begins to record your time and distance manually.
