When people think of shoulder training, they generally think of presses and raises rather than pulls. But the high pulley rope pull, or face pull, is the exercise that has helped me the most so far in terms of my rear delt development. Dana is technically not doing face pulls (more like upper chest pulls), but the movement is the same for this exercise.
Rear delt and upper back training is extremely important for opening up the chest and pulling your shoulders back for every day life.
