This machine was engineered to take away the risks of this essential exercise and give you the freedom of using your max weight safely and comfortably. Exclusive DuraFirm pads surround your shoulders for comfort through brutal leg workouts. Perform traditional floor squats or step up to the 20-degree angled diamond plate foot platform for increased development of your quads and glutes. The innovative calf raise block is round instead of square, eliminating the painful edge and providing a deep pre-stretch for huge gains in size and strength. This machine can handle squats of 300, 500, 800 lbs. and more! The extra heavy-duty 3" x 3" high tensile strength steel mainframe and all-4-side welded construction make it the strongest machine in its class. Weight posts are Olympic size only. Dimensions: 62"L x 43"W x 56"H. Warranty: In-Home LIFETIME Warranty
