We could get into cardio vs strength training and as one that does both cardio isn't even close to being beneficial if not properly done it's a negative if over doing it.* I added bolded emphasis in the above
I agree that resistance training is an important part of maintaining health. I would say that cardio is equally, if not more important, as high VO2 max seems to be one of the better predictors of positive health outcomes and longevity. There is burgeoning evidence that lifting too much, can reduce lifespan/longevity. I don't think there has been shown a similar "cap" with cardio/aerobic.
Btw, curious if you take any exogenous testosterone and/or anabolic enhancing chemistry (and I don't mean creatine and other legal supplements)?
As far as supplement zero i do do creatine as everyone should yes everyone 5to 10 grams daily along with lean animal protein per grams of targeted weight you Want to be 170 it's 170 grams of protein.
Carbs generally used post workout or during workouts not walking so many eat way ro many. I wouldn't possibly eat as many as you do and believe I cardio way way more than most.
