Develop strength, speed and lean muscle tone with the Sunny Health & Fitness No. 077 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 simply adding or subtracting bands, each band adds approx. 22 lbs of resistance.
