Exercise Advice: Position yourself in a hack squat machine with your back pressed firmly against the pad. One foot should be set firmly on the platform and the other should be out of the way. Begin this exercise by squatting on one leg as though you are going to sit down in a chair. Squat to a point to where your thigh becomes parallel to the floor and then return to the start position. Do this for 8 – 10 repetitions and then repeat with the opposite leg.
