Cable Rear Delt Fly
Instructions
- 1Adjust the pulleys to the appropriate height and adjust the weight. The pulleys should be above your head.
- 2Grab the left pulley with your right hand and the right pulley with your left hand, crossing them in front of you. This will be your starting position.
- 3Initiate the movement by moving your arms back and outward, keeping your arms straight as you execute the movement.
- 4Pause at the end of the motion before returning the handles to the start position.

About Cable Rear Delt Fly
The cable rear delt fly isolates the rear head of the deltoid, often the most neglected of the three. Standing between two pulleys set at shoulder height, arms crossed in front of you, you spread the arms back while keeping the elbows slightly bent. The crossed cables keep continuous tension across the whole range, ideal for this small muscle that is hard to 'feel'. This exercise improves posture and rebalances a shoulder dominated by pressing movements. Chase the contraction as you spread, without shrugging or pulling with the traps.

warningCommon mistakes
- warningBending and straightening the elbows like a row
- warningPulling with the traps instead of the rear delt
- warningUsing loads too heavy that break form
- warningBringing the hands too low toward the hips
- warningRushing through reps without controlling the return
tuneVariations and alternatives
- tuneLow-cable rear delt fly — arms sweep up and out from a low pulley, a more vertical angle that emphasizes the upper part of the rear delt.
- tuneSingle-arm cable fly — unilateral work that corrects left/right imbalances and increases range of motion through torso rotation.
- tuneRope face pull — bent elbows, recruits the external rotators and upper back more, complementing the rear delt.
- tuneBent-over dumbbell rear delt fly — cable-free version, useful as a backup or at home, but less constant tension at the bottom.
person_checkWho it's for and level
The cable rear delt fly suits anyone who has trained for a few months and feels their rear delt is under-worked despite regular shoulder sessions. It is especially useful for lifters who do a lot of pressing and push-ups, since these movements create an imbalance favoring the front delt. Beginners can add it as soon as they understand continuous muscular tension, without necessarily chasing heavy load. More advanced athletes use it as a finisher, often supersetted with an overhead press, to fix a visual and functional weak point on the back of the shoulder.
shieldSafety and precautions
The main risk with the cable rear delt fly is using too much weight, which turns the movement into an upper-back pull rather than isolated rear delt work, with a risk of repeated shoulder irritation. Keep the elbows slightly bent and fixed throughout the movement: locking them out or bending them more changes the exercise and stresses the elbow joint. Avoid any jerky start, the pull should stay smooth and controlled. If you feel pain at the front of the shoulder or neck discomfort from compensatory trap shrugging, reduce the load and check your position before continuing.
calendar_monthWhere to place it in your program
Place the cable rear delt fly at the end of a shoulder session, after heavy pressing movements like the overhead press, so you don't pre-fatigue a stabilizing muscle before the main effort. It works well for 3 to 4 sets of 12 to 20 reps, with continuous tension and a one-second pause at full spread. Many lifters also include it in back sessions, alongside a row, since the rear delt contributes to horizontal pulling. Two sessions a week, 48 hours apart, are usually enough to progress this small muscle group without excess fatigue.
helpFrequently asked questions
How is it different from the face pull?
The cable fly keeps the arms straight and isolates the rear delt more, while the face pull bends the elbows and recruits the upper back.
What height should I set the pulley?
A pulley at shoulder height or slightly above gives a good horizontal angle to target the rear of the shoulder.
Cable or dumbbell fly for the rear delts?
The cable keeps constant tension and isolates the rear delt very well; dumbbells, bent over, are simpler but let the load off at the bottom. The cable is often superior for this tricky-to-recruit muscle.
How many sets and reps for the cable rear delt fly?
3 to 4 sets of 12 to 20 reps are enough, using a light to moderate load that lets you really feel the rear delt contracting through the full range.
Can you do the cable rear delt fly with one arm?
Yes, the single-arm version helps correct an imbalance between shoulders and slightly increases range of motion by rotating the torso away from the working arm.
Do you need to warm up before the cable rear delt fly?
One or two light sets are enough to wake up the shoulder, since the exercise uses modest loads that don't require a heavy warm-up like a press does.
Can the cable rear delt fly replace the face pull?
They're complementary rather than interchangeable: the cable fly isolates the rear delt better with straight arms, while the face pull, with bent elbows, works the external rotators and upper back more.
Should the cable rear delt fly be done before or after the main shoulder press?
Always after: it works a small stabilizing muscle that shouldn't be pre-fatigued before heavier pressing work, where shoulder stability matters for a safe, strong lift.
Why is the rear delt so hard to feel working?
It's a small muscle that's rarely the prime mover in daily life or in most compound lifts, so the mind-muscle connection takes longer to build than for bigger, more frequently used muscles.
