Elliptical Trainers: The Treadmill Alternative
Elliptical trainers can provide much the same aerobic and cardiovascular benefits as treadmills, and burn as many calories. Elliptical trainers are also lower-impact than treadmills, and many people prefer them for that reason.
Elliptical machines don't directly train your body for any specific sport, although the motion can be similar to cross-country skiing. If you're training to run a road race, you'll want to train on a treadmill when you can't be outdoors. If you're training for a triathlon, elliptical trainers will help your endurance and cardiovascular fitness, but you'll need to use a stationary bike to get in shape for the cycling portion. If you're going Mountain climbing, stair climbers can help build the leg and glute muscles you need more
specifically than elliptical trainers will.
A particularly nice thing about elliptical machines is the reversible motion that helps work your lower body in a unique way. You won't go as fast, and thus it will be less of a cardio workout, but using elliptical trainers in reverse is a great way to exercise your quads and other lower body muscles.
Elliptical machines have become extremely popular in the last few years precisely because they do things differently. And studies continue to show that you can burn just as many calories on elliptical trainers as you can on treadmills. For lower impact, involvement of the upper body, variability and the ability to work different muscles, elliptical trainers are hard to beat.
A personal trainer at the gym can help you explore the options for working out on elliptical trainers, and manufacturers often provide extensive workout guides and suggestions if you are considering buying an elliptical trainer machine of your own.

Resistance Systems For Elliptical Trainers
Treadmills and stationary bikes have various levels of difficulty and resistance in order to fulfill the needs of a variety of people in a variety of stages of fitness. As you work out more and more and become more fit, you need to gradually increase the effort you put into each workout. In addition to that, in order to get the most from your workout, it is best to increase the speed or energy you are expending throughout the workout, and slow it back down to cool off.
When you are just walking or riding a regular bike, you can control this easily, by changing the terrain (ie, going up a hill) or changing the speed. Elliptical trainers are no different. There is a wide variety of models on the market, all of which come with a different resistance system. The differences in the resistance system affects the price of the elliptical trainers, as well as the type of workout you are going to receive.
The different resistance systems of elliptical trainers can be categorized in three ways: magnetic resistance, electromagnetic or particle brake system, and the eddy-current resistance system. The cheapest is the manually adjusted magnetic resistance system, and you will typically find those in elliptical trainers that are under four hundred dollars.
The particle brake resistance system for elliptical trainers does not have to be manually adjusted, and it can be programmed, but it does respond slowly when you are trying to adjust it. The best system is the eddy-current system, which has a chrome-plated flywheel with a very fast rpm speed. These are the most expensive, but it is a totally silent resistance system.
