Short answer: face pulls mainly train the rear deltoids, the rotator cuff muscles that rotate your arm outward, and the mid-back muscles that pull your shoulder blades together. They are one of the better cable exercises for shoulder health, but the popular claim that they will single-handedly "fix" rounded shoulders is stronger than the evidence behind it.
The muscle-activity research is reasonably clear about what is doing the work. EMG studies of shoulder exercises — including work from Ann Cools' research group in Belgium, which has spent years mapping rotator cuff activation — consistently show that horizontal pulling with external rotation lights up the posterior deltoid, infraspinatus and teres minor (two of the four rotator cuff muscles), plus the middle and lower trapezius and the rhomboids. That combination matters: the external rotators are chronically undertrained in most gym programs, which are heavy on pressing and internal rotation, and the lower and middle traps are the muscles that keep the shoulder blade anchored while your arm moves overhead.
The posture claim needs more honesty. Rounded, forward shoulders are usually blamed on "tight chest, weak back," and while strengthening the retractors and external rotators is a sensible part of addressing that, there is no good trial showing face pulls alone change resting posture in a lasting way. Posture is heavily influenced by habit, total training balance, workload, and how many hours a day you spend in one position. What the research does support is the shoulder-health angle: rotator cuff and scapular muscle strengthening programs reduce shoulder pain in overhead athletes and lifters, and exercises in this family are a staple of those programs. Stronger external rotators also tend to tolerate pressing volume better, which is the real prize for most lifters.
Execution details the evidence and coaching experience agree on: pull toward the forehead or eye line rather than the neck, let the rope ends finish beside your ears with the knuckles rotated back, keep the weight light enough that your lower traps do the squeezing instead of your arms turning it into a row, and control the return. Most people get more from 12–20 honest reps than from loading it like a strength lift.
So file face pulls under "high-value accessory for shoulder balance and durability," not "posture cure." Two or three light sets a few times a week is cheap insurance for shoulders that have to survive years of benching and overhead work.
Where do face pulls sit in your program — a planned staple, or an afterthought when your shoulders feel beat up? And has anyone here actually had shoulder niggles improve after adding dedicated external rotation work?
