The Sole R52 Recumbent exercise bike helps keep your 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 cycle. 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.
