I agree, sometimes health issues put a damper on things
In my 60's and after having a leg amputated i was more concerned about my body and muscles atrophying . I do 2-3x a week mild to heavy cardio workouts at the local health club
IMO, unless you're working out on a set schedule trying to maintain a physique you had in your 20's. Forget about it. Accept the fact as one gets older you get a little wider here, little grayer there. I'm not condoning weight where you're up 2-3 belt sizes, just know some things change. Unless you can maintain a set amount of time to the health club and keeping to a diet change. You have to accept it
