Not all cross trainers are created equal. Cross training refers to working various parts of the body by combining different exercises in a variety of ways. Typically one activity or sport trains certain parts of the body but not others. Cross training aims to eliminate this. Cross trainers are generally non-impact machines (sometimes called 'ellipticals') which refers to a specific motion. All ellipticals are cross trainers but not all cross trainers are ellipticals. More results in less time. Research shows that the CYBEX Arc Trainer burns more calories than any other cross trainer or elliptical cross trainer tested. The science behind the Arc Trainerﾒs big calorie burn is the Arc motion. It engages the right muscles ﾖ quads and glutes ﾖ that demand lots of energy from the body when they are called upon to work. That means big calorie burn. And ... because the Arc is demanding of the muscles ﾖ not the joints, it can be used longer without putting a strain on the knees, hip or back.
