Position yourself in front of a barbell loaded with a suitable lifting weight. Adopt a very wide stance with feet turned slightly outward and head remains up. Bend forward from the hips and take position with an overhand grip on the barbell, no wider than shoulder-width. This is the starting position.
Commence the movement by exhaling and driving out of the base position with the legs extending, the hips pushing forward and your shoulder blades retracting which forces the torso straight up. In the finishing position, the legs are fully extended, the head is up and the arms hang directly down from the shoulders.
Reverse the movement by bending from the knee and hip until you are back in the starting position, inhaling as you do.
