Natural and Ergonomic Using a recumbent bike keeps the body aligned in a more natural position while working out thereby reducing overall strain and fatigue. The low-impact cycling motion and ergonomic frame design decrease stress on knees, hips, and the lower back while maintaining the same positive cardiovascular effects of riding an upright bike. This makes a recumbent ideal for any level workout whether a beginner, taking part in rehab or physical therapy, or for more intense training and exercise. The R52’s easy to use program features and large LCD display with 10 programming choices— including two user-defined options—offer users a direct line of focus to their fitness goals.
