Doing that sounds like you’re lifting more weight for more reps than would be optimal for recovery and growth. In other words, if you did that for most of your sets you would overtrain your CNS very quickly.
Honestl;y I think you are Over playing this “overtraining” thing. as an excuse Not to work hard. Sure you can overtrain but the body can also adapt to Major stressors . But you must teach it to do so by giviong it HIGH stress.
No knock against pound4pound (I haven’t read many of your posts), but I would tend to agree. Look at John Davies workouts. People would always criticize him for his high stress workouts, but you know, he produced great results (whatever you think of unstable surface training).
Up until modern equipment, farmers had to do high stress work every day, all year.
Or the Bulgarian O lifters.
Or european strongmen.
Or elite military units. Sure, different kind of stress, but if you can make it through the blitzkrieg and mental breakdown of BUD/S and Hell week, you can do anything.
90% of all overtraining is mental.
Besides, that’s what off weeks are for.
