Row Low-Pulley Standing One-Arm

Standing one-arm low-pulley rows strengthen and develop muscles of the upper and middle back. This allows the lifter to isolate the contraction of the latissimus dorsi, middle trapezius, rhomboids and teres major as the scapula retracts on each side. This exercise requires the stabilization of the torso and leg muscles, thereby increasing the difficulty of row execution to complement back exercise performance and overall hypertrophy of the back muscles.

The isolation of shoulder extension and scapular retraction to one side also increases activation of the latissimus dorsi. Performing rows with a cable provides constant resistance throughout the entire range of motion.

In addition to serving as an exercise that enhances the aesthetics of the upper and middle back, standing one-arm low-pulley rows also complement weightlifting and sport performance.

The latissimus dorsi is a broad, flat, and triangular-shaped muscle of the lower back. When defined, the “lats” form a “v” shape of the torso as they angle toward the waist. The latissimus dorsi is a primary shoulder adductor and shoulder extensor. In this exercise, the latissimus dorsi is responsible for extending the shoulder as the D-handle approaches your torso. Its origin is located along the spines of the lower six thoracic vertebrae, lower 3 to 4 ribs, and iliac crest of the pelvis. Its insertion spirals around the teres major as it inserts into the intertubercular groove of the humerus.

A flat and triangular muscle, the trapezius is the most superficial muscle of the posterior thorax. The middle fibers run horizontally to the scapula. Its origin is located at the occipital bone, ligamentum nuchae, and spines of C7 and all thoracic vertebrae. Its insertion is located along the acromion and spine of the scapula and lateral region of the clavicle. The middle trapezius retracts the scapula. As a superficial muscle, developing the middle trapezius contributes to the overall aesthetics of the upper back.

The rhomboids are two rectangular muscles that lie underneath the trapezius just below the levator scapulae. The rhomboids consist of the rhomboid minor and rhomboid major. The rhomboid minor is located above the rhomboid major and is more superficial. The origin of the rhomboid minor is located at the spinous processes of C7 and T1. The origin of the rhomboid major is located at the spinous processes of T2-T5. The insertion of both rhomboids major and minor is located at the medial border of the scapula. The rhomboids are synergists with the middle trapezius when retracting the scapula.

The teres major is a thick muscle located underneath the teres minor. It helps to form the posterior wall of the axilla. A synergist of the latissimus dorsi, the teres major extends the shoulder in this exercise. Its origin is located at the posterior surface of the scapula at the inferior angle. Its insertion is located at the crest of the lesser tubercle on the anterior humerus (its tendon fused with that of the latissimus dorsi).

The deltoid is a thick, multipennate muscle that forms a curtain around the shoulder. It is the primary muscle involved with arm abduction. When developed, the deltoids give the shoulder their round shape. The extension of the shoulder joint as the D-handle is pulled toward your torso activates the posterior fibers of the deltoid. The origin of the deltoid is located at the insertion of the trapezius, lateral third of the clavicle and the acromion spine of the scapula. Its insertion is located at the deltoid tuberosity of the humerus.

The biceps brachii consists of two heads, the long head and the short head. The long head tendon helps stabilize the shoulder joint and its origin is located at the tubercle and lip of the glenoid cavity of the scapula (shoulder blade). The short head origin is located at the coracoid process of the scapula (shoulder blade). The long and short head unite as the muscle bellies run down the front of the arm. Both heads merge, sharing insertion into the radial tuberosity of the elbow joint. The biceps brachii flexes the elbow joint as the D-handle is pulled toward you.

The brachialis lies underneath the biceps brachii, originating at the front of the lower end of the humerus bone. Its insertion is located at the coronoid process of the ulna at the elbow joint. The brachialis is a primary elbow flexor.

The erector spinae muscle group of the back consists of the quadratus lumborum, iliocostalis, longissimus, spinalis, and semispinalis. These muscles stabilize the torso as it flexed forward at the hips. The abdominal muscles, consisting of the rectus abdominis, external oblique, internal oblique, and transverse abdominis, help stabilize the torso during this exercise. The hamstrings and quadriceps leg muscles stabilize the body as the weight is lifted.

The rotator cuff muscles help stabilize the shoulder joint as the scapular retract and the shoulder extends. The wrist flexors maintain the wrists rigid and stabilized throughout the exercise.

Focus more on the shoulder extension and scapular retraction to pull the D-handle as opposed to focusing on the hand dominating the effort of the lift. This will not only optimize muscle activation, but also prevent strain on the biceps brachii that could increase the risk of injury.

Adjusting the cable height to elbow height allows the lifter to perform a standing one-arm row from a different angle with torso upright. Performing row variations from different angles optimizes muscle fiber activation. In the long run, this promotes strength and hypertrophy of the back muscles.

Alternating to seated variations of the row (e.g. seated row, one-arm seated row) allows the lifter to execute the row while omitting low back and leg fatigue that may be associated with the standing position of this exercise. This increases force production while the back muscles are further isolated.

Focus on the concentric portion of the contraction, concentrating on “squeezing” as the upper arm reaches the level of your torso.

Emphasis on eccentric contractions, prolonging the eccentric portion of the contraction, may also be incorporated in a training program focused on increasing strength. This should be implemented accordingly and with adequate muscle recovery as eccentric contractions cause substantial damage to muscle tissue.

It’s important to note that your repetition and set volume will depend on your goals (e.g. strength, hypertrophy, muscular endurance). It is also important to allow adequate recovery days in between back, shoulder, and biceps training days to allow muscles to repair.

Using momentum to lift the weight (e.g. bending and flexing the torso for assistance) minimizes the potential of force production of the involved muscles and can increase the risk for back injury. It is important that both the eccentric and concentric phases of the exercise are controlled.

Solely using the arm to pull the weight minimizes the activation of the scapular retractors. Simultaneously retract scapula and extend the shoulder to pull the D-handle toward you.

If the lifter has a compromised range of motion with the back or shoulder joint and/or performs this exercise incorrectly, this exercise can increase the risk of injury and/or exacerbate a previous injury.

If proper technique and recovery are not adhered to, biceps injury, rotator cuff injuries, and/or lower back injuries may occur.
