Cable Rear Delt Fly is best learned as a controlled sequence, not a race from the first position to the last. The exercise mainly trains rear delts, while rhomboids, middle traps, and rotator cuff help support and control the movement. You will use a dual cable machine and D-handles while working from standing in a stable stance.
What makes a good Cable Rear Delt Fly repetition?
Keep the ribs quiet and move the arms without turning the rep into a shrug or back bend. The movement has a clear, scalable pattern. Start light, learn the positions in order, and progress only while every repetition remains controlled.
Muscles worked
Primary
Rear delts
These muscles should carry most of the intended work when the setup and movement path stay consistent.
Supporting
Rhomboids, Middle traps, and Rotator cuff
These muscles assist the movement or help keep the rest of your position steady.
Set up before you move
Start from standing in a stable stance. Set your hands and feet so the position feels balanced before the first repetition. Check that a dual cable machine and D-handles are secure and adjusted before you begin.
Step-by-step tutorial
How to do Cable Rear Delt Fly
- 1
Cross the cable grips
Stand centered, hold opposite cable handles with arms forward at shoulder height, and brace the torso.
Breathing: Breathe steadily; do not hold your breath.
- 2
Open both arms
Exhale and sweep the arms outward until they align with the torso while the elbows stay soft.
Breathing: Exhale through the effort.
- 3
Return to crossed reach
Inhale and bring the handles forward under control without rotating the body.
Breathing: Inhale through the controlled return.
Common mistakes to avoid
Starting before the setup is stable
Do not rush the first position. Stand centered, hold opposite cable handles with arms forward at shoulder height, and brace the torso. Make that setup feel repeatable before adding speed or resistance.
Letting the working position drift
Keep your starting alignment consistent through the rep. If another part of the body has to swing or twist, reduce the load or range.
Rushing the return
The return is part of the exercise, not a pause between efforts. Inhale and bring the handles forward under control without rotating the body.
Forcing a range you cannot control
Pulleys at shoulder height; cables crossed; right hand holds left cable and left hand holds right cable; arms open horizontally; torso fixed.
Sets, reps, and rest
Start with 2–4 sets of 10–15 smooth repetitions. Rest 45–90 seconds between sets. Use enough resistance to feel the target muscles without shortening the range or borrowing momentum from the rest of your body.
Treat this as a starting framework. Your load and volume should match your current technique, recovery, and training plan.
