Maybe a personal max. I suspect the older you are when you start lifting the lower that max is going to be. What you are essentially saying is that weight training for strength is counterproductive. This is illogical.
I used to be able to bang out reps on the bench w 315 when I was in my thirties. Now, I rarely go over 225 , if I bench at all. For some reason, I feel a strain in the shoulder and know if I try to get back up to 315 for reps, I'll likely rip or tear something. Not worth it just to get a big number up there any more.
See what I'm saying? I'm not going to gain anything trying to max out bench but would likely get a tear or injury and not be able to train. Just not worth it.
I train my fng balls off almost daily, just smarter. No crossfit bs w the kipping and oly lifts w a barbell, etc. No dumbass movements you see all over the place.
