@dawn16 So is the take away if you can't do bench at a 8-10rpe, you shouldn't do it? That sounds ridiculous to me. You may not get 100% hypertrophy gains, but you will still gain. And on top of that, I'd guess a lot of people probably who train at a 7rpe and don't like pushing into the 9-10rpe range are nursing some type of injury or are worried about getting injured.
I have a number of friends who swore off bench entirely after getting a shoulder injury (is there anyone that has gone through weightlifting and not injured a shoulder doing something stupid?), but imho, most injuries come when you are pushing to 9-10rpe.
It's tough to find the balance. I think isolation exercises are easier to go to a higher rpe, (like your cable press, which I love), but I think doing compound exercises at a 6-7rpe would still be immensely beneficial to most people, would it not? Or is it that at that point, there are better alternatives (like you mention).
My only thing with progressive overload is I think it slowly outpaces the speed your tendons and ligaments can strengthen at, so it can be tough to judge sometimes.
