The lat pull down is one the the best exercises for building the latissimus dorsi muscles that can give you a ‘V-back’ look. Many athletes do wide grip, behind-the-neck lat pulls to maximise the load on the muscles. Most experts discourage athletes from doing this exercise because it increases the risk of neck and shoulder rotator-cuff injuries. A study published in the Journal of Strength and Conditioning Research found that a pronated-grip (palms away) lat pulls, in front of the chest, overloaded the lats best. Grip width (space between the hands) had no effect on activation of the lat muscles. The pronated grip was superior to the supinated (palms toward the body) grip for activating the lats.
