Hello BBM!
I recently met a fellow who has undergone brain surgery. He is altering his training from hitting 600+ lb deads and squats to doing no more than 225 or so.
In his case, I guess, this question is not hypothetical - if an individual trained in a steady state fashion (squatting/deadlifting around two plates, benching around 185, cardio for x minutes per week) does that individual still benefit from a health perspective as time reaches years and years? Or is it the case that once you adapt to a given level of stress the benefits start to diminish? Another way to ask the same question - do you actually need progressive overload to train for health benefits vs getting continually stronger?
