Elliptical Trainers

Elliptical machines are here to stay. People with bad knees love them, as they allow a good aerobic workout without any pounding on the knees. The technique seems awkward at first, but can be learned fairly easily. Beginners can take it easy, and advanced aerobic exercisers can use a combination of incline and resistance to work as hard as they want. If you buy an elliptical for home use, be careful to find one that´s well made, since the cheaper models may not hold up.
