The squat has always been the best overall leg exercise working all of the muscles of the lower body. Until now, the only way to perform this great exercise was to use a barbell, which is difficult and can be dangerous due to lack of balance. The Powertec Leverage Squat/Calf L-SC13 machine duplicates the precise pattern of the squat but instead utilizes a lever arm rather than the bar. With the Powertec Leverage Squat Calf L-SC13 you receive the benefit of the proper feel and natural resistance of a barbell with the control and safety of a machine. The Powertec Leverage Squat Calf L-SC13 incorporates a “Patent Pending” start/stop handle that allows you to begin and finish the exercise in the top position. There are two large diamond plate platforms for angle of flatfooted squats. The angle position really allows for perfect and comfortable motion eliminating much of the stress on the lower back. The removable calf block comes standard with the unit and allows for standing calf raises to be performed.
