Stand holding a barbell overhead with your arms fully locked out.
Pull your shoulders blades back and down towards your buttocks.
Initiate the movement by flexing at the hips, knees and ankles until your thighs are parallel to the ground.
Your back must remain straight and upright throughout the movement with the head up and your gaze forward.
Keep your knees inline with your toes and do not allow your heels to rise of the ground.
Stand by pushing through your hips and returning to standing position.
