Performing the: A Step-by-Step Tutorial Barbell Squat
Stand up to lift the barbell off the rack, take a step or two back and position your feet shoulder-width apart, toes slightly pointed outwards.
Begin the squat by bending your knees and hips, lowering your body as if you're sitting back into a chair, until your thighs are parallel to the floor, keeping your back straight and chest up.
Push through your heels to stand back up to the starting position, making sure to keep your back straight and head up.
Repeat this process for the desired number of repetitions, then return the barbell safely to the rack.
