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.
