Adjust the machine and secure the belt. Stand with feet shoulder-width apart, toes slightly out. Engage your core and maintain an upright torso. Lower your body by bending at hips and knees, chest up, knees aligned with toes. Descend until thighs are parallel to the floor (or as far as mobility allows). Push through heels to return to the starting position, fully extending hips and knees. Repeat.
Ensure a snug, comfortable belt fit. Distribute weight evenly across both feet. Keep knees tracking over toes. Maintain a neutral spine by engaging your core. Control the descent, avoid bouncing. Use a full range of motion.
