The Arc Trainer is a totally unique exercise machine. The science behind the Arc Trainer's big calorie burn is the arc motion. It engages the right muscles -- quads and glutes -- that demand lots of energy from the body when they are called upon to work. That means calorie burn and, because The Arc Trainer is demanding of the muscles -- not the joints, it can be used longer without putting a strain on the knees, hip or back. My personal impression: the Arc Trainer allows no impact on the joints to improve my endurance sustainable.
