Key points: 1) footing between hip and shoulder width apart, feet should be externally rotated a bit 2) place your feet in front of you a bit - that is, higher up on the platform so that when you descend into your squat, your knees don't jut forward over your feet 3) make sure your knees are tracking in-line with your feet and ankles during the squat 4) maintain contact between your sacrum (low back hip area) and the back pad of the machine 5) actively press your hips back into the back pad of the machine if necessary to maintain contact 6) drive through your squat from the center of your feet, not the ball nor the heel, but over the arch 7) squeeze the handle near the shoulder pad in order to exit the machine safely
