Not addressing seeking hypertrophy or "getting big".
Nothing wrong with wanting to "get big," but our focus is maintaining fitness and functionality. Furthermore, not all male bodies, or few female bodies, can "get big" anyway. It depends on physical architecture mostly, and also how much time you want to put into one thing. Some people do heavy weights 3-4X/wk. Heavy. I don't have the time or vanity, so fine.
Well, I do have my share of vanity but whatever. Sun's out, guns out. I do not wish to be unattractive to my wife, for starters. I do not want to be a lazy, sedentary, late middle-aged slob although that might be fine.
Anyway, What's the best heavy weights routine for general conditioning? I used to do them 5X5 three times/wk, but I wanted or needed to do 2 days of HIIT cardio and about 2 days of calisthenics, and it got to be too much. Satisfying, but too much.
My trainer now has me doing high reps with weights - like 15 warm-up, then 12/10/8/6. It's hard. Might be better for me. I'd be better off adding 4 sets of deads/wk, maybe. Can do that.
