The R3i recumbent exercise cycle is an excellent combination of comfort and durability, offering you low-impact exercise that’s easy on your knees, hips, and lower back. Superior comfort starts with an oversized molded seat bottom and ventilated seat back to keep you cool while exercising. The seat back of the gym cycle includes extra lumbar support and is adjustable to your preferred angle. Finally, the seat is designed with full length armrests with integrated heart rate sensors, so you can monitor your heart rate constantly throughout your workout without needing to move your hands or wear a chest strap.
