good advice, i'm going to start doing those exercises in my routine, though i have rows already.
ya, face pulls (10-20 reps), trap bar deads (better for you now than regular, ~10 reps), rear fly (10-20 reps), single arm rows (8-15 reps), reverse pushups (to failure)/reverse pushup holds for time emphasizing pinching back of shoulder blades (to failure) etc, neutral back extensions (bodyweight to ailure), db shrugs rotating your shoulders back at the top (nice and controlled, 8-15 reps).
if you don't have access to a trap bar, deadlift off pins for a while..bar a little below knee height.. really focus on form/posture rather than ego-lifting.
pC!
