Rear-delt and upper-back glue with just a loop band.
Lead with the elbows high and externally rotate so your knuckles end up by your ears.
Pulling a band toward your forehead with hands splitting wide trains the rear delts as the prime movers, with the upper back muscles squeezing the shoulder blades together to finish each rep. The external rotation at the end, knuckles rotating back beside your ears, is what separates a proper face pull from a lazy row and what makes it such effective medicine for pressing-heavy programmes. It's the rare exercise that pays off in both looks and shoulder health, which is why coaches sneak it into almost everything.
Several times a week is fine, they're low fatigue and most people's rear delts and upper back are chronically undertrained. Two or three sets at the end of upper sessions, or as a daily movement snack, both work.
You're pulling with your hands instead of leading with your elbows. Lighten the tension, drive the elbows high and wide first, and think about your knuckles finishing beside your ears, not your hands touching your face.
Face height or slightly above. Anchoring too low turns it into an upward row and cramps the rotation, too high and it becomes a pulldown. Eye level keeps the pull tracking straight at your forehead.
