There is no reason at all at 40+ years old to be doing this. Think more reps with compound movements, think sweating and getting that heart rate up.
You want to think about being able, capable, and functional for daily activities. For example - cool you bench 100 lb db - but if you are gassed the f out like that fat bastid Kamali after 10 seconds of actual exertion, what the heck is the purpose of this?
Awesome job in the gym. But if your goals are to get back to where you were, doing the same things when we were 25 is not going to yield the same results at 45.
It's better to do 225 with the wide grip, instead of jerking those dumbbells into the launch position. I don't do presses with dumbbells anymore (not for shoulders or for chest). Barbells are safer and easier. And with a wide grip, you can squeeze the pecs the same way as you can with the dumbbells.
I used to rep 315 no problem on the bench. Now - I never go above 225. Last time I tried 315, I felt this weird thing in shoulder like it was going to result in a tear. If we are injured, we can't train. If we can't train, then what? The cost / benefit analysis simply doesnt make sense to go really heavy any more.
We all want to see you succeed here. 
Any exercises that hurt my joints or tendons I either don't do at all or do them dead last after fatiguing the muscle with other exercises.
For triceps, overhead extensions are done last (if at all), after dips. And they're done with a cable. Of course, last year during the lockdowns, I had no choice but to do skull crushers and overhead extensions. But, for some reason, using water jugs as weights didn't hurt my elbows that much. Perhaps, it's due to the center of mass shifting while moving.
