Barbell Back Squat
Position: Stand with feet shoulder width apart, or slightly wider, with toes pointing slightly out. The bar should be resting across the upper traps. The abdominals should be “Braced.” (“Bracing” consists of tightening your abdominals as if you were going to take a punch to the stomach).
Movement: Initiate the movement in the hips by sitting the hips back and down
(as if you were trying to sit in a chair that is just a little too far out behind you). Continue the downward movement until the Femur (thigh) is parallel, or slightly below parallel, to the ground. Return to the starting position by driving hard through your heels and extending your hips. Then repeat.
