How to do a machine seated reverse fly

Master setup, range of motion, and tempo with step-by-step instructions so every rep is more effective and safer.

About machine seated reverse fly

The machine seated reverse fly is an effective way to isolate the posterior deltoids and upper back muscles like the rhomboids. The fixed path of the machine helps eliminate momentum, ensuring that the rear delts perform the majority of the work. This exercise is crucial for maintaining shoulder health and achieving a balanced look, especially for those who perform a lot of chest pressing movements.

Instructions for Proper Form

Setup:

  1. Seat Adjustment: Sit on the machine, facing the pads. Adjust the seat height so the handles are roughly aligned with your chest when your arms are extended forward.
  2. Chest Pad: Ensure your chest is firmly pressed against the pad throughout the entire movement.
  3. Grip: Grasp the handles with a neutral grip (palms facing each other) or a pronated grip (palms facing down), depending on your preference and the machine design.

The Lift:

  1. Initiate the Fly: Exhale and pull the handles back, opening your arms wide, leading with your elbows. Keep your back straight and imagine pulling your shoulder blades together.
  2. Peak Contraction: Pause briefly at the end of the movement, feeling the contraction in your rear delts (back of the shoulders) and upper back muscles.
  3. Controlled Return: Inhale and slowly return the handles back to the starting position, resisting the weight as it comes forward.

Tips:

  • Elbow Position: Keep your elbows slightly bent and pointing upwards throughout the movement.
  • Focus on the Rear Delts: Concentrate on using your rear deltoid muscles to pull the handles back. Avoid using momentum or swinging your body.
  • Avoid Excessive Movement: Keep your torso stable and avoid arching your back as you pull.
  • Variations: Some machines allow you to adjust the angle of the movement. Experiment to find the position that best targets your rear deltoids.

Common mistakes: Leading with the hands instead of the elbows, shrugging the shoulders up, and letting the weight plates slam between reps.

Alternatives

machine seated reverse fly(parallel grip)

The machine seated reverse fly with a parallel grip is an isolation exercise specifically designed to target the posterior deltoids and rhomboids. By sitting facing the machine and pulling the handles outward, you strengthen the muscles responsible for pulling the shoulders back. This exercise is vital for improving posture, shoulder health, and developing the rear portion of the shoulder complex for balance.

The cable rear delt row is a specialized movement targeting the posterior deltoids and upper back muscles. By using a cable machine, you maintain constant tension throughout the entire range of motion, which is difficult to achieve with free weights. This exercise is crucial for developing well rounded shoulders, improving posture, and counteracting the forward leaning tendencies often caused by heavy chest and front side training.

cable crossover reverse fly

This isolation movement targets the posterior deltoids and the muscles of the upper back. Using cables ensures that there is tension on the muscles even at the start of the movement. By pulling the handles across the body in a wide arc, you improve shoulder health, posture, and the overall definition of the rear shoulders, balancing out chest heavy training routines effectively.

The cable seated rear lateral raise is a precise isolation exercise designed to target the posterior deltoids and upper back muscles. Using cables ensures that the muscles remain under constant tension during both the lifting and lowering phases. This movement is essential for improving shoulder health, posture, and creating a rounded, three dimensional look to the shoulders that free weights sometimes fail to provide.

The dumbbell incline rear lateral raise is a specialized isolation movement designed to target the posterior deltoids. By lying chest down on an incline bench, you stabilize your torso and prevent cheating, ensuring the rear shoulders do the majority of the work. This exercise is vital for developing a balanced shoulder physique and improving overall shoulder health and stability.

The cable standing rear delt row is an excellent isolation exercise for the posterior deltoids and the muscles of the upper back. By pulling the cable toward your face or upper chest, you emphasize the rear shoulders, which are often neglected in standard routines. This exercise is crucial for maintaining shoulder health, improving posture, and developing a thick, well proportioned upper back and shoulder area.

The dumbbell rear delt row targets the posterior deltoids and the upper back muscles like the rhomboids and traps. By rowing dumbbells with an emphasis on pulling the elbows back and out, you specifically engage the often neglected rear shoulders. It is essential for maintaining shoulder health, improving posture, and achieving a well rounded, muscular look from both the back and side views.

resistance band kneeling face pull

The resistance band kneeling face pull is a highly effective exercise for shoulder health and upper back development. By kneeling and pulling the band toward your face while flaring your elbows, you target the rear deltoids, rhomboids, and external rotators. This movement is crucial for counteracting the effects of rounded shoulders and improving overall posture and shoulder stability in a controlled manner.

This exercise focuses on the often neglected posterior deltoid muscle located on the back of the shoulder. By leaning forward and raising dumbbells out to the sides, you improve shoulder symmetry and posture. Strong rear delts are crucial for stabilizing the shoulder joint during heavy pressing movements and for creating a complete, rounded look to the upper body and shoulders.

The band standing rear delt row is an excellent accessory exercise for targeting the posterior deltoids and upper back muscles. Using a resistance band allows for peak contraction at the end of the movement, which is crucial for improving posture and shoulder health. It is particularly effective for balancing the anterior dominance often found in many lifting routines, enhancing overall shoulder symmetry.
