The face pull is a shoulder and upper back exercise that improves the key muscular groups.  By doing face pulls exercises daily, mainly the rhomboids, trapezius, and deltoids, all are targeted. Rhomboid muscle - The rhomboids are placed between your scapulae and under your middle trapezius.   Pull your shoulder blades together just like the mid-traps. Rhomboid major and minor are the two rhomboid muscles, and both are engaged in face pulls.   Trapezius- The trapezius is a big, diamond-shaped upper back muscle. The function of three sets of fibres is determined by their alignment. In a movement known as depression, the lower traps pull your shoulder girdle downward.   The elevation is a movement in which the upper fibres pull your shoulder girdle upward. Retraction occurs when the middle fibres pull your scapulae, or shoulder blades, back and together.   Deltoids- The deltoid muscles are divided into three groups: anterior (front), medial (side), and rear posterior.  Your upper arm is controlled by the three deltoids working together. During face pulls, the posterior deltoids are very active.
