Elliptical/Arc Trainers

The elliptical trainer has become one of the most popular pieces of equipment in health clubs and in some home gyms--you will surely see these in the commonly known gyms like LA Fitness and 24 Hour Fitness. These combine the movements of a stair stepper, a bicycle and cross-country ski machine. It was designed so that your legs move in an oval (or elliptical) pattern while your arms move handles back and forth for a full body workout.

This low-impact machine is gentle on the joints, especially the knees and quite simple to use--which makes it a great workout for those who have arthritis.

Science suggests that these workouts may improve the quality of life and well-being as well as combatting fatigue.
