If you work out at a health club you probably noticed that in the last few years there are fewer treadmills, because they are being replaced by elliptical trainers. And although treadmills still outsell ellipticals in total numbers, elliptical sales are growing at a faster rate.
­What is dri­ving the popularity of elliptical trainers? The­re are two factors tha­t make elliptical trainers so appealing:

Low Impact Workout

Upper and Lower Body Workout

B­enefits of a Low Impact Wo­rkout
Most types of exercise req­uire some type of impact and/or reverse action. For example, when you walk each step is impacting force on your ankles, knees and lower back. That impact is minor in comparison to running, which can be as much as 2.5x your body weight. Ov­er the years that constant pounding can result in long-term injuries and strains.
Elliptical trainers reduce the hazards of impact through an ­elliptical motion.It feels like you are naturally walking or running without any real impact or reverse action, and­ yet it is a weight be­aring exercise that contributes to building muscle an­d bone density.
If you look at the side of an elliptical trainer you'll notice the shape of the motion is like a flat circular pattern. Budget ellipticals tend to be more circular and bouncy, whi­le quality mac­hines have a­ flatter circular motion and more of an even stride. Regardless, the elliptical moti­on significantly reduce­s the impact to your joints, and that is why elliptical trainers are appealing to older individuals and p­eople with injuries. It is becoming the­ exercise machine of choice fo­r the ­"baby boomers."
Benefits of an Upper and Lower Body Workout
The concept of exercising the upper and lower body simultaneously is revolutionary. An elliptical workout utilizes the­ quadriceps, hamst­rings, glutes, chest, back, triceps and biceps. There is no other machine that offers this benefit. You are not only exercising more muscle group, you are also optimizing your energy expenditure. That mea­ns it is taking less time to achieve more results, lik­e burning calories and increasing your cardio capacity. A number of­ elliptical trainers all­ow you to reverse the motion, the­reby emphasizing resistance to even more parts of your muscles.
By exercising more of your muscle mass you improve fat mobilization, which results in burning more calories and building muscle endurance more efficiently. Certain exp­erts have suggested that this dual action process reduces the perceived rate of exertion. In other words, you are exercising harder without a noticeable difference from a less strenuous work­out.
The benefit of an upper and lower body workout, combined with low impact ex­ercising, are the ­reasons why elliptical trainers are so popular. And there is one other feature that should be noted. I­n comparison to treadmills, elliptical traine­rs require considerably less maintenance. That i­s due to the fact there are fewer moving parts, and less wear from impact.
If you haven't tri­ed an elliptical trainer, get to your local health club or a fitness equipment store and take one for an elliptical spin­. Avoid the budget models and test the machines tha­t are at least $1,000+. They have a more natural elliptical motion and are more stable an­d dura­ble.
You'll find­ that an elliptical trainer can have a major impact on your health and fitness.
