How To Do

  1. Find a dual cable machine with both pulleys open for use.
  2. Adjust the cable setting to about the height of your head. 
  3. Latch on the handle attachments to each cable pulley. 
  4. Position yourself directly in front and the middle of both cable pulleys with feet shoulder-width apart. 
  5. Grab the handles in the opposite hand (e.g., the left pulley handle is gripped with the right hand). 
  6. Both arms should be extended and crossed over each other. If need be, take a step back to create enough space to extend the arms out for the exercise’s movement. 
  7. Keep a neutral grip with palms facing each other. Maintain a slight bend in the elbows.  
  8. Squeeze your shoulder blades together and keep the back straight. 
  9. Decide which arm you want on top or under the other for the crossover movement. Another option is to alternate for each repetition.
  10. Draw the cables across your body to the other side and as far back as possible. 
  11. Slowly return to the starting position. 
  12. Repeat for the desired number of repetitions and sets.

Tips From Expert

  • Think of extending your arms out to the side like you’re about to give someone a big bear hug. Use this visual cue to extend the arms to the sides for crossover movement. 
  • Do not flex your wrists during the movement. All the movement should primarily be happening at the shoulder joint to better engage the upper body muscles. Avoid placing unnecessary strain on the wrist joints. 
  • Prioritize maintaining a slight bend in the elbow throughout the movement. This reduces strain on the shoulder and wrist joints and better engages the targeted muscles.

Optimal Sets and Reps

The ideal sets and reps can vary depending on your personal fitness goals. For example, a bodybuilder typically focuses on hypertrophy over endurance training, performing more sets and fewer reps.

How to Put in Your Workout Split

The standing cable rear delt fly is an upper-body exercise that targets the posterior deltoids. The upper trapezius muscle is also active during this movement. The exercise utilizes a dual cable pulley machine to perform the crossover motion and place tension on the rear delt muscles. 

This exercise should be incorporated into upper body days or alongside other cable shoulder workouts for upper and lower body splits. Regarding muscle-focused splits, like back and biceps, the standing cable rear delt fly would be best suited for shoulder or arm days. For push and pull split programs, this exercise would be best suited for pull days.

Determining your fitness goals is advantageous for lifters as this can emphasize your training focus, such as hypertrophy or endurance. When adding this exercise to your workout split, ensure you perform the correct sets and repetitions for your goals. 

This movement is a compound exercise incorporating multiple joints and muscle groups. Ideally, it should be performed near the beginning rather than the end of the workout, as it requires more energy. Begin with a lower weight to prioritize form, before increasing intensity with heavier loads.

Primary Muscle Groups

Posterior Deltoid

Muscles located at the back of your shoulder. Helps with posture.

Posterior Deltoid

The posterior deltoid is one of three heads that comprise the shoulder's deltoid muscle. It is located at the back of the shoulder. This muscle externally rotates the shoulder, extends the arm backward, and brings the arm away from the body horizontally (horizontal abduction). 

A healthy posterior deltoid is essential for maintaining a strong shoulder joint and promoting various arm movements. Humans use the posterior deltoid in everyday actions like pulling a chair out, opening doors, and waving their arms. 

In the standing cable rear delt fly, the posterior deltoid is engaged to aid the backward pulling motion of the cables. The cable is drawn behind the body using the rear delts as the primary muscle activated during the movement.

Secondary Muscle Groups

Upper Trapezius

Triangular shaped muscles located between your neck and shoulder blades.

Upper Trapezius

The upper trapezius is the smallest section of the broad trapezius muscle. The trapezius muscle is shaped like a flat triangle across the shoulders, neck, and back. The upper trapezius forms the top of the shoulders and the base of the neck. 

This muscle is necessary for everyday movements. It is responsible for extending and rotating the neck and for lifting the arms. This muscle is used to turn one's head to glance in the car's rear-view mirror and shrug one's shoulders.

The upper trapezius is engaged in the standing cable rear delt fly when the arms lift and draw the cables back. Strengthening this muscle is important for supporting the spine and maintaining healthy posture.

Equipment

Single Grip Handle

Wide Cable Pulley Towers

These provide a good range of cable exercise using wider lever points for a bigger range of motion. Ensure you don't drop the cables when lifting.

Single Grip Handle

This can be attached to a cable machine and used for a wide range of unilateral resistance exercises. Ensure you keep a firm grip.

Variations

Exercises that target the same primary muscle groups and require the same equipment.

Alternatives

Exercises that target the same primary muscle groups and require the different equipment.

Who Should Do?

Bodybuilders

Bodybuilders are notorious in the fitness world for establishing impressive and dominating physiques. These gym-goers and lifters actively participate in training to promote hypertrophy and develop these award-winning muscled appearances. 

Establishing a record-breaking physique, including hypertrophy of the deltoid muscle, is no simple task. That’s why bodybuilders must insert exercises like the standing cable rear delt fly. This exercise better targets muscles like the posterior deltoids to promote hypertrophy. 

Lifters Wanting Bigger Shoulders

Any lifter wanting to develop bigger, more defined shoulders should prioritize the standing cable rear delt fly. This exercise is necessary for targeting the posterior delts and engaging the upper trapezius muscles to promote muscle growth

Shoulder development can be tricky since there are three different heads to activate when it comes to the deltoid muscle. Not every shoulder exercise engages all three deltoid heads. 

We now know that the standing cable rear delt fly comes in handy to activate the posterior deltoid head. 

To target other parts of the deltoid, consider adding other exercises to your routine. For example, the overhead press targets the anterior deltoids, and the lateral raise activates the medial deltoid. 

Individuals Looking To Improve Posture

Many things, including weak muscles or muscular imbalances, can cause poor posture. The way you sit can also contribute to poor posture in your everyday life. This can have a detrimental effect on your physical fitness. 

Exercises like the standing cable rear delt fly aid in developing stronger muscles to support good posture. There are also rear delt bodyweight exercises that can be done at home for individuals without gym memberships. Fixing sitting posture and strengthening these muscles can be productive ways to correct rounded shoulders and forward head posture. 

Who Should Not Do?

Anyone With An Upper Body Injury

You may need to avoid this exercise if you have an upper-body injury. Whether it be a shoulder, wrist, or upper back injury, this exercise can place unnecessary tension on these areas. 

When injured, it is highly recommended that you seek the help of a healthcare professional, like a physical therapist. They will be able to guide you if you need to reduce the strain or stress on the affected area. We want to avoid causing an increase in inflammation and pain, potentially risking further injury. 

Benefits Of The Exercise

Supports Shoulder Function 

The posterior deltoid supports shoulder function, including horizontal adduction, internal rotation, and joint flexion. This means moving your arm out to the side, turning it inward, and raising it above your head. During pulling movements, the rear delt stabilizes the shoulder joint when bearing heavy loads and when lifting objects. 

Weak deltoid muscles can affect daily movements. Healthy shoulders help us perform numerous daily actions, such as lifting groceries and opening a car door. Performing exercises like the standing cable rear delt fly is a good way to prevent weak shoulders from affecting our day-to-day lives. 

Reduces Lower Back Strain

Lower back pain affects close to 10% of the world’s population. A strong and healthy upper back can reduce strain on the lower back. In conjunction with exercises that target the lower back, training the upper back, shoulders, and neck can decrease lower back pain

The standing cable rear delt fly actively targets the posterior deltoids and upper trapezius. Inserting this exercise into your workout routine, in combination with lower back exercises, can be more effective in reducing lower back pain. 

Improves Posture

Strengthening the posterior deltoids and upper trapezius can improve posture. These muscles support correct posture in different ways. 

The posterior deltoid stabilizes the shoulder joint, preventing the shoulders from rounding forward. It works alongside muscles like the upper trapezius to keep the shoulders back and reduce forward head posture. The upper trapezius supports the spine; strengthening it reduces poor posture habits like hunching. 

Poor posture can have negative effects if unaddressed, like reduced mobility and muscle strength. It can also cause discomfort and pain in the lower back, neck, and shoulders. Strengthening these areas and incorporating correct posture in your day-to-day life can improve posture.
