Your legs wonít call this a Sissy Squat. Talk about a direct transmission of resistance to your legs! And with only your body weight! Youíre held in place by foot rollers and a contoured pad that is adjustable for different tibia lengths. Then, keeping the hips rigid, lean backward from the knees up. Yeah, it ainít easy. Your quads will feel like lava in no time. Itís a whole lot of leg devastation in a very small footprint. The frame is all welded from three-inch square tubing, and the adjustment surfaces are chrome-plated for scratch resistance.
