The Cybex R-Series Arc Trainer is a premium commercial-grade cardio machine designed to deliver maximum calorie burn with minimal joint stress. Featuring Cybex's patented Arc movement pattern, it allows the user's knees to move behind their toes—reducing stress on the knee joints while heavily engaging the glutes and hamstrings. With versatile resistance levels and intuitive incline/stride controls ranging from Glide to Climb modes, users can target different muscle groups for everything from low-impact recovery to high-intensity interval training. Built with heavy-duty construction, integrated accessory trays, and an accessible console interface, the Cybex R-Series is an ideal center-stage addition to any commercial fitness facility or home gym setup.
