Develop strength, speed, and lean muscle tone with the Sunny Health & Fitness No. 077S Row-n-Ride Home Squat Machine. This exerciser promotes compound movement (two or more muscle groups working cohesively) to strengthen not only your lower body but also your shoulder, arms and back. Activating multiple groups of muscles requires more energy, so you ll burn more calories throughout your workout. Compound exercises bring compounded results! With 3 adjustable resistance bands, intensify your workout by adding or subtracting bands - each band adds approximately 22 pounds of resistance.
