Develop strength, speed, and leanness with the Sunny Health & Fitness NO. 077S  Home Squat Machine. Strengthen 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 require more strength, so you'll burn more calories. 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!
