No joke, progressive resistance training (weightlifting) for older people can be better bc it has cardio built in but takes less time and is more precise so you can really manage exertion well. It signals the body to retain muscle so you can intermittent fast w/out losing ability while on a caloric deficit and w/out inflammation and other crap while on a surplus, making it easier to keep precancerous bodies swept up. I am not actually old yet, but I plan to be old.

Also, people may not realize poor sleep hygiene can reduce your physical strength by 30% (measured by resistance training) or maybe more due to coordination issues
