Magnetic Cross Trainer With Adjustable Seat provides a total body (legs, hips, buttocks, arms and shoulders), low-impact, cardiovascular workout for all family members, regardless of ability level. This unit resembles a walking or jogging machine. Your feet move in a natural elliptical motion, providing a no-impact workout for less stress on the joints. As you walk, your hands grasp poles that move in conjunction with your leg motion. This results in a smooth, fluid movement that tones arms, chest, back, hips, legs, and glutei.
