Elliptical Cross Trainers
Elliptical machines, or cross trainers, combine the exercise motions of some of the most popular pieces of equipment: treadmills, stair climbers and exercise cycles. The end product is a low-impact machine that gives a great cardiovascular workout and works a wide range of lower body muscles.
Cross trainers are a great way to exercise the upper and lower body with very low impact to the joints. Ellipticals can be used in both forward and reverse motions, changing the focus of the muscle groups which are trained.
