بنام خدا هفت ورزش اشتباه وارائه صحیح آنها No. 1: Lat Pull-down Behind the Head The problem: Only people with very mobile shoulder joints can keep their spines straight enough to do this exercise properly. So the move — done wrong — can lead to shoulder impingement or worse, a tear in the rotator cuff. And if the bar hits the back of the neck, it could injure cervical vertebrae. A Safer Lat Pull-down On the pull–down machine, lean back a few degrees, use a wider–than–shoulder grip, and bring the bar down in front of your body to the breastbone, pulling shoulder blades down and together. Contract your abdominals to stabilize the body, and avoid using momentum to swing the bar up and down. The lat pull–down works the muscles of the upper back.
