The Squat Bench (SissySquat) is one of the most simple but necessary tools we have for the lower body. This station takes pressure away from knees while directly stimulating the quads and glutes.
The Squat Bench allows you to focus on the muscles used rather than the balance taken for a conventional squat (great for newbies). It exaggerates the concentric, upward movement with quads and glutes while making it easier to control the eccentric portion before flexing those muscles for another rep.
