This is a funny myth that developed from a few idiot using way more weight than they can manage... If you warm up and then do a 5 set pyramid-up in weight, there should be no issue with pulling to the rear as long as you work in a controlled fashion, and grind out slow, smooth reps (no bouncing)... The same goes for shoulder presses behind the neck....
Actually you're funny, the way you always post like you're the last word. hahahahahh
Behind the neck presses and pulldowns both cause shoulder impingement, an established condition that is harsh on the joints and potentially injurious. It is NOT a figment of your deluded, arrogant imagination; it's a fact & something that i've experienced. Warming up and using reasonable weight will mitigate but not remove the potential for injury. Using a controlled manner will help to reduce but not remove possible problems; realistically most who traing hard won't keep an entirely controlled cadence for the entire set anyway. It might be worth trying these exercises but be there will always be the potential for problems given the inherent pressures exerted on the shoulders.
A better alternative for behind the neck presses IMO is to do 1/2 or 2/3 motions that avoid the bottom portioin of the ROM that is the most stressful to the joints. This is one where a Smith machine can also help.
Stop posting opinionated misinformation on here like it's fact; someone will pay the price
