The lever seated reverse fly (parallel grip) is a rear-delt isolation exercise performed on a leverage machine with palms facing each other throughout the movement. It primarily targets the posterior deltoid, with the infraspinatus, teres minor, and both the middle and lower fibers of the trapezius acting as synergists. The fixed machine path makes it a consistent option for building rear shoulder thickness and improving scapular health.
Cómo hacer el Lever Seated Reverse Fly (parallel grip)
- 1Adjust the seat height so the handles are at shoulder level when you sit facing the machine.
- 2Sit facing the pad with your chest lightly against it and your feet flat on the floor.
- 3Reach forward and grasp the handles with a parallel grip — palms facing each other, thumbs wrapped fully around the handles.
- 4Begin with your arms extended in front of you, elbows very slightly soft rather than fully locked.
- 5Brace your core, keep your spine neutral, and retract your shoulder blades slightly before initiating the movement.
- 6Exhale and sweep both arms out to your sides in a wide arc, leading with your elbows and keeping your palms facing each other throughout.
- 7Continue until your arms are roughly in line with your torso or as far as the machine allows without discomfort, squeezing your rear delts and mid-back at the end of the arc.
- 8Hold the contracted position for one count.
- 9Inhale and return the handles along the same arc under control until your arms are back in the starting position in front of you.
- 10Repeat for the desired number of repetitions without allowing your torso to rotate or your chest to lift away from the pad.
Consejos de técnica
- Keep your palms facing each other for the entire set — allowing the wrists to rotate changes the effective grip and reduces posterior deltoid engagement.
- Lead the movement with your elbows rather than your hands; think about pulling your upper arms back and apart rather than pulling the handles.
- Maintain light chest contact with the pad throughout to prevent your torso from swinging and taking momentum into the movement.
- Use a controlled two-second return on every rep — the eccentric phase under a parallel grip places significant load on the infraspinatus and teres minor, making slow negatives especially productive.
- Choose a weight that allows full range of motion; shortening the arc to handle heavier loads shifts stress away from the posterior deltoid and onto the upper trapezius.
Errores comunes
- Allowing the wrists to rotate out of the parallel grip during the arc, which changes the line of pull and reduces isolation of the posterior deltoid.
- Using momentum by jerking the handles outward, which removes tension from the rear delts at the start and places sudden stress on the shoulder joint and rotator cuff.
- Lifting the chest off the pad during the pull, which allows trunk rotation to take over and shifts effective load away from the target muscles.
- Shrugging the shoulders toward the ears, which recruits the upper trapezius instead of the intended posterior deltoid and mid-trapezius synergists.
- Setting the seat too low or too high so the handles are not at shoulder height, shifting stress to the upper or lower trapezius instead of centering it on the posterior deltoid.
Preguntas frecuentes
What muscles does the lever seated reverse fly (parallel grip) work?
The primary target is the posterior deltoid — the rear portion of the shoulder. The infraspinatus, teres minor, trapezius middle fibers, and trapezius lower fibers act as synergists to support and stabilize the movement.
How is the parallel grip different from a pronated grip on the reverse fly machine?
A parallel (neutral) grip keeps the palms facing each other throughout the arc, which places a slightly different rotational demand on the shoulder and can feel more comfortable for people with wrist or shoulder impingement issues. A pronated grip (palms down) tends to recruit the upper trapezius slightly more. Both versions target the posterior deltoid, but the parallel grip allows many lifters to achieve a fuller range of motion without discomfort.
How many sets and reps should I do on the reverse fly machine?
For rear delt hypertrophy, 3 to 4 sets of 12 to 20 repetitions with a moderate weight is a common approach. The posterior deltoid responds well to higher rep ranges and controlled tempos. Prioritize a full arc and a deliberate squeeze at the end of each rep over loading heavy weight.
Where should I feel the lever seated reverse fly?
You should feel the primary contraction at the back of the shoulder — the rear deltoid — along with some engagement across the upper back between the shoulder blades. If you feel the work mostly in your neck or upper traps, you are likely shrugging; focus on keeping the shoulders down and driving the elbows back and apart.
Where does the reverse fly fit in a shoulder or back workout?
The lever seated reverse fly is an isolation exercise and works best near the end of a shoulder or back session, after compound pulling movements such as rows or pull-ups. Placing it later in the workout allows the larger back muscles to handle the heavy compound work first while still leaving enough fatigue for a focused rear delt finish.
