How can I effectively use a squat machine to maximize my workout?

To effectively use a squat machine and maximize your workout, focus on proper form by keeping your back straight, feet shoulder-width apart, and knees aligned with your toes. Start with a comfortable weight and gradually increase as you get stronger. Perform controlled movements, lower yourself down until your thighs are parallel to the ground, then push back up through your heels. Aim for 3-4 sets of 8-12 reps with proper rest in between.
