The Total Body Arc Trainer provides effective, low-impact training with less knee stress than walking. The 21 incline adjustments result in motions that mimic gliding, striding and climbing. Up to 1200 watts of available power make the Arc Trainer perfect for both strength and power training.
We used one of these at our gym and finally decided to buy one - and cancel the gym. This is our favorite exercise machine, and it has been fantastic. We use it every day and feel great afterward!
