Lateral Raise Incline Bench

The incline bench cable lateral raise activates the posterior deltoid, as it is the primary horizontal shoulder abductor. Activating the posterior deltoid contributes to the overall hypertrophy of the shoulder muscles, providing roundness and a fuller appearance.

Although it is primarily an exercise for aesthetics, incline bench lateral raises also serve as an auxiliary exercise that can increase strength involved in other multi-joint exercises.

Performing this exercise in a lying position allows the lifter to further isolate the movement to their upper body. Performing this exercise with a cable provides constant resistance throughout the entire range of motion.

The deltoid is a thick, multipennate muscle that forms a curtain around the shoulder. It is the primary muscle involved with arm abduction and the posterior fibers are a primary horizontal shoulder abductor. When developed, the deltoids give the shoulder their round shape. 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 infraspinatus is one of the four rotator cuff muscles. Partially covered by the deltoid and trapezius, it assists with horizontal shoulder abduction. Its origin is located at the infraspinous fossa of the scapula. Its insertion is located at the greater tubercle of the humerus, near the insertion sites of the supraspinatus and teres minor.

The teres minor is also a rotator cuff muscle that can be regarded as the “sidekick” to the infraspinatus. It is located just below the infraspinatus and may be inseparable from the infraspinatus. It comes as no surprise that the teres minor performs the same actions as the infraspinatus. Its origin is located at the lateral border of the dorsal subscapular surface. Its insertion is located just below that of the infraspinatus on the greater tubercle of the humerus.

The latissimus dorsi, rhomboids, wrist extensors and other two rotator cuff muscles (i.e. supraspinatus and subscapularis) play an essential role in stabilizing the wrists, forearms and shoulders during this exercise.

Incline bench dumbbell lateral raise, bent over lateral raise, seated bent over lateral raise, high cable reverse fly.

Periodically rotating your wrists (grasping the end of the cable without a D-handle attached to it) can stress your deltoid from an additional angle, optimizing hypertrophy.

Strategically varying your incline bench angle within the 30-45 degree range can optimize the stress placed on your deltoid from differing angles.

Perform lateral raises for posterior deltoids from different positions such as bent over lateral raise and standing straight with a cable (high cable reverse fly).

Focus on the concentric portion of the contraction, concentrating on “squeezing” as the arms approach shoulder level.

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 shoulder training days to allow muscles to repair.

Raising the hands above the level of the elbow and shoulder can minimize the activation of the deltoid and place negative stress on the shoulder joint.

Swinging the torso and/or moving the legs throughout the movement minimize the activation of the working muscles and increase the risk for injury. Do not use body momentum to lift the weight during concentric phases. Do not drop the weight on its way down. The concentric and eccentric phases should be controlled.

If the lifter has a compromised range of motion with the shoulder joint and/or performs this exercise incorrectly, this exercise can increase the risk of injury and/or exacerbate a previous injury. Performing this exercise with a weight too heavy for the lifter can also increase the risk for injury.

If proper technique and recovery are not adhered to, impingement syndrome, rotator cuff injuries, and glenoid labrum tears may result.

Lifters with a history of shoulder injury or present state of injury should consult with a physical therapist or orthopedic physician before performing this exercise.
