Elliptical trainer

An elliptical trainer combines a smooth, oval-shaped foot motion with a push-and-pull arm motion via moving handles. Because the feet never leave the pedals, the movement is impact-free and gentle on the joints, yet still works the whole body broadly. The machine raises the heart rate efficiently and develops endurance in the lower limbs and upper body at the same time. Adjusting resistance, and incline on some models, lets you scale the intensity from light to hard.
