Tone, Tighten and Lift with the Sunny Health & Fitness No. 077 Upright Row-N-Ride Bike Exerciser. Strengthening not only your lower body but your shoulders, arms and back, this exerciser promotes compound movement (two or more muscle groups working cohesively). Activating groups of muscles together, requires more strength, so inevitably, burns more calories. With 3 adjustable resistance bands, intensify your workout by adding or subtracting bands, each band adds approx. 22 pounds of resistance!!
