How to do machine seated reverse fly(parallel grip)
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
This machine variation isolates the back of your shoulders (rear delts) by locking your torso in place against a chest pad. By using a parallel grip (palms facing each other), you often get a more natural shoulder path that helps you feel the muscle work without your traps taking over the whole movement.
It is a perfect 'finisher' or accessory lift. Because the machine guides the weight, you can focus entirely on the squeeze and the stretch rather than worrying about your lower back or swinging the weights.
Why Use It
- Isolates the rear delts with minimal risk of using momentum.
- The chest support removes lower back strain common in bent-over versions.
- Parallel grip provides a comfortable, joint-friendly path for most lifters.
When to Use It
Perform this after your heavy rows or pull-ups. It works best as a high-rep accessory to 'fill out' the back of the shoulder once the big compound movements are done.
Stats
Instructions for Proper Form
Setup
- Seat Height: Adjust the seat so that when you grab the handles, your arms are parallel to the floor.
- Chest Pad: Sit facing the machine and press your chest firmly against the support pad.
- The Grip: Grasp the vertical handles with a parallel grip (palms facing each other).
Execution
- The Initiation: With a slight bend in your elbows, pull the handles out to the sides in a wide arc.
- The Squeeze: Focus on pinching your shoulder blades together as your arms move back.
- The Peak: Stop once your elbows are slightly behind your shoulders. Hold for a split second.
- The Return: Slowly bring the handles back to the starting position, resisting the weight the whole way.
Pro Tip: Imagine you are trying to push the walls away from you rather than just pulling the handles back. This helps keep the tension on the rear delts.
Common Mistakes
- Shrugging: Lifting your shoulders toward your ears. Keep them pressed down.
- Chest Lifting: Arching your back and pulling your chest off the pad to use momentum.
- Locked Elbows: Keeping the arms perfectly straight can put too much stress on the elbow joint.
Mistakes by Level
Beginner
- Using too much weight and shrugging the shoulders.
- Bouncing the weight stacks at the bottom.
Intermediate
- Not reaching a full contraction at the back.
- Moving too fast through the return phase.
Advanced
- Losing tension at the very end of the range.
- Allowing the traps to take over the movement.

Setup Requirements
- Adjust the seat so the handles are level with your shoulders.
- Press your chest firmly against the pad.
- Grab the vertical handles with palms facing each other.
- Keep your feet flat on the floor for a stable base.
Form Checklist
- Is my chest staying on the pad?
- Are my shoulders staying down (not shrugging)?
- Am I leading with my elbows?
- Is the movement smooth or am I jerking the weight?
Range of Motion
Pull back until your elbows are in line with your torso. Avoid pulling so far back that your chest leaves the pad.
Breathing Pattern
Exhale as you pull the handles back; inhale as you slowly return to the start.
Tempo Guidance
Use a 2-0-2-1 tempo: 2 seconds back, no pause at the start, 2 seconds forward, and a 1-second squeeze at the peak.
Caution Notes
- If you feel a pinch in the front of your shoulder, slightly lower the seat height.
- Don't let the weights slam together at the bottom; keep tension on the muscle.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Rear delt hypertrophy
- Improving posture
- Shoulder health and stability
Goal Tags
Rep Ranges
- 10-15 reps for muscle growth.
- 15-20 reps for endurance and metabolic stress.
Set Guidance
3-4 sets of 12-15 reps.
Rest Guidance
60-90 seconds between sets.
Frequency
2-3 times per week as part of a pull or shoulder day.
Pairings
- Pair with Face Pulls for extra rear delt focus.
- Pair with Chest Press for an upper-body push/pull superset.
Audience Notes
- Excellent for beginners who struggle to feel their rear delts with dumbbells.
- Great for advanced lifters to use as a high-volume finisher.
Substitution Targets
- Dumbbell Rear Delt Fly
- Cable Face Pull
- Band Pull-Aparts
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Band Pull-Aparts
Easier to control and requires no machine setup.
Best for: Learning to engage the rear delts.
Progressions
Single-Arm Reverse Fly
Increases core demand and allows for a deeper focus on each side.
Best for: Correcting muscle imbalances.
FAQ
Common Questions
Should my arms be straight?
No, keep a slight, fixed bend in your elbows to protect the joint and keep the focus on your shoulders.
Why do I feel this in my neck?
You are likely shrugging your shoulders up. Focus on keeping your shoulders 'down and back' throughout the set.
