Elliptical trainers are exercise equipment that combine the movements of the stair climber, treadmill and the exercise bike into one. These machines combine the movements and benefits of hiking, cross country skiing, and biking. One of the best things about elliptical trainers is they don’t create any impact, so it’s easy on your joints. Not only do these machines provide a great cardio workout, they tend to help you burn more calories than a treadmill or stationary bike. Many models have dual action handle bars, so you can exercise your entire body and get a true cross training workout. This is an ideal workout for those who prefer not to run or jog.
