Dumbbells only. Full back.
Bent-over rows for the lats, pull with the elbows, squeeze at the top, don’t yank with the arms.
Then open the angle for traps. Control the stretch, don’t shrug sloppy.
Finish with rear-delt work. Slight bend in the elbows, lead with the pinkies, pause when the shoulders are packed.
Slow the negative. Light enough to feel the muscle, heavy enough that the last reps actually matter.
3–4 sets. Save it and run it twice a week.
