I don't know, I see what you're saying, but I don't think there's evidence that shows that following some sort of bodybuilding/powerlifting/running routine (on an amateur level, not as a professional) is detrimental to one's health in any way. Human body thrives on being challenged after all, but challenged in a way that it can recover and grow stronger. Without challenge there is only stagnation and deterioration.
Is it healthier to workout hard, within reason, rather than sitting on the couch eating hot pockets and playing video games....yes. Is it healthier to pound your body with weights and eat to compensate for such vs just living an active lifestyle and eating light and healthy....no way.
Does not mean your body can’t take it, does not mean you won’t recover, does not mean you won’t live to be 90 but make no mistake your body does not enjoy being pounded with unnatural weight and having your heart repeatedly stressed unnaturally.
This is coming from a guy who pounds his body with weights regularly. But I have no illusions about what I’m doing, I’m doing it for vanity. Every “built” guy and former athlete I know has severe issues from it, from their joints to their stomach to their heart. I have a friend built like a Greek god any guy would wish to look like and he can barely pick his kids up because his joints are so bad and has to take blood pressure meds and has big time gut issues. I’ve been lucky myself but it will catch up to me, although I stopped going really heavy a long time ago from looking at what happened to other guys.
