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.
