7 Gym Machine Shoulder Workout (Top Exercises, Muscle Worked)

Our shoulders are one of our most important joints and muscles. Strong shoulders help us lift heavy weights and prevent injuries. They also improve our posture and strengthen our upper body.

Strong and healthy shoulders are essential for everyday activities, as well as for many sports and exercises.

We need to train all three heads of the deltoid to build, but it cannot be easy to work all parts of the shoulders with free weights.

Gym machines are a great way to build up those shoulders.

Gym machines offer several advantages over free weights. Machines allow you to isolate and work all three heads of the deltoid to build a bigger and stronger shoulder.

This blog will discuss the following:

  • Benefits of using gym machines for shoulder workouts.
  • Top gym machines For shoulder workouts
  • How to do the exercise correctly.
  • We will also give you a shoulder workout plan.

Let’s Dive In. Keep reading and practicing.

Shoulders Anatomy And Function

In fitness, “shoulder exercises” refers to resistance exercises that target the deltoid muscle. The shoulder is a “ball-and-socket” joint between the upper arm’s humerus bone and the scapula bone (shoulder blade).

Six main movements that occur at the shoulder are flexion, extension, abduction, adduction, internal rotation, and external rotation.

The deltoid muscle of the shoulder consists of three separate sections or heads.

You need to work all three of them, along with the trapezius muscle in the upper back, to build an impressive shoulder.


Anterior Deltoid

It is commonly called the front delt. It arises from your collar bone and inserts into your humerus (upper arm bone).

Your front delt’s main function is to move your arm up, forward, and to your center. 

Lateral Deltoid

It has a few common names, such as side delts and middle delts. It arises from a little area on the shoulder blade called the acromion process and inserts into the humerus.

Your lateral delt’s main function is shoulder abduction, which is bringing it up to the side.

Posterior Deltoid

It is also known as the rear delt. It arises from the spine of the scapula (upper part of your shoulder blade) and inserts into the humerus.

Your posterior delts main function is moving the arm outward and backward.


It is often called the trap, a large triangular-shaped upper back muscle.

The main function of the traps is to support head movement, stabilize certain arm motions and provide stability in pushing and pulling movements.

Top Gym Machines For Shoulder Workouts With Exercises

Having strong, stable shoulders is a key fitness goal for many gym-goers.

While free weights like barbells and dumbbells are effective tools, it is important to consider shoulder workout machines when developing your shoulder training regimen.

Machines help isolate muscle groups, improve form, and make it safer to lift heavier weights overhead.

Here are 10 gym machines that you can use for a complete shoulder workout:

1. Shoulder Press Machine

The Shoulder Press Machine, sometimes called the “Military Press Machine,” is a staple in gyms and fitness centers worldwide. This machine is specifically designed to target the shoulder muscles, as it provides a controlled environment for overhead pressing movements. It is an excellent exercise for building the front and side deltoid muscles.

Machine presses have advantages over free-weight presses, providing better stability and safety.

They also offer a choice of handgrips. A neutral grip (palms facing together) focuses more on the anterior deltoid better than a pronated grip (palms forward).  

This exercise requires very strict movement because the bar is fixed to the rack, and the weights can go much lower. This gives the front deltoid muscles a good stretch.  

Shoulder Press Machine

Muscles Worked

  • The primary muscles worked are the front and side deltoids.
  • Secondary muscles include the triceps, upper trapezius, and serratus anterior.

How Does It Work?

  1. Sit with your back against the backrest and your feet flat on the floor.
  2. Depending on the machine’s design, grip the handles with an overhand or neutral grip (palms facing each other). Make sure your grip is secure and comfortable.
  3. Bend your elbows at about a 90-degree angle and keep them level with your shoulders.
  4. Now press the handles overhead until your arms are nearly locked out.
  5. Lower the handles back to the starting position under controlled motion.

2. Smith Machine For Shoulder Workout

The Smith Machine is a gym apparatus known for its guided barbell system. This allows movements to be safer and more controlled than traditional free weights.

While it is often used for various exercises such as squats and smith machine bench presses, the Smith Machine is also an excellent addition to your shoulder training regimen as well.

For shoulder workouts on the Smith Machine, the muscles targeted can vary based on the exercises chosen. However, here are some of the most commonly targeted shoulder muscles:

  • Smith Machine Overhead Press: It primarily targets the shoulder muscles and helps to build strength and mass.
  • Smith Machine Upright Row: Pulling the barbell towards your chin will engage the deltoids and upper and Middle trapezius.
  • Smith Machine Behind Neck Press: This emphasizes the side and rear delts more. Carefully press the bar up from behind your head, being cautious not to strain your neck.
  • Rack Pulls: Focus on the lower traps, latissimus dorsi, and erector spinae.
  • Smith Machine Shrugs: This exercise primarily targets the upper trapezius and rear deltoids muscle. It’s a simpler movement but effective for adding strength and size to the upper shoulders and neck region.
  • Bent-Over Rows: Target the latissimus dorsi, rhomboids, and middle trapezius.
  • Smith Machine Rear Delt Row: It targets the rear deltoids and helps to improve posture and upper back strength.

  6. Engage your core and press the barbell upwards,
  7. Slowly lower the barbell back down to the starting position.
  8. Perform your desired number of repetitions and sets.

3. Double Pulley Cable Machine

The Double Pulley Cable Machine is a versatile and effective piece of gym equipment that offers a wide range of exercises for muscle targeting and isolation. Unlike free weights, the cable machine provides constant tension throughout the range of motion.

Featuring two adjustable pulleys, this machine allows you to perform an array of pulling and lifting movements from various angles, optimizing your shoulder training for strength, hypertrophy, or endurance.

Here are some effective shoulder exercises you can perform on this versatile machine:

Cable Lateral Raise

Muscle Worked During Cable Lateral Raises

Cable lateral raises focus primarily on the side deltoid muscles while working the anterior deltoid, as well as both the middle and lower traps.

How Does It Work?

  1. Attach a single-grip handles to the lowest point of the cable pulley system. 
  2. The handle from the right pulley should be in your left hand, and the handle from the left pulley should be in your right hand. The cables should be crossed and pulled tightly.
  3. With elbows slightly bent, raise your arms to shoulder level, leading with the elbow.
  4. Slowly lower your arms back down until you feel a stretch in your delts and repeat.

4. Pec Deck Machine (Reverse Fly Machine)

The Pec Deck Machine is traditionally used for chest exercises, but can be adapted for a Reverse Fly to target your upper back and shoulder muscles. The Pec Deck Machine usually consists of a seat, back support, and two arm pads or handles that can be adjusted to various angles.

For the Reverse Fly, you’ll be using the machine in a way that’s opposite to the conventional pec deck fly. It is a simple yet effective exercise that increases deltoid muscle definition and strength. The pec deck rear delt machine fly targets your upper back muscles and shoulder muscles, particularly the rear deltoids, (backside of your shoulders)Traps and rhomboid.

The Rear delt fly machine provides consistent resistance throughout the entire range of motion. Additionally, this machine offers various technical adjustments, such as grip positions, trajectory, and range of motion settings.
