For Older Muscle Quality, Lifting Weights Beat Supplements and Cardio
This review suggests resistance training is the best-supported way to improve muscle quality after 60.
Looking at dozens of trials in adults over 60, resistance training was the only thing that clearly improved muscle quality (strength relative to muscle size). Cardio, combined training, and nutrition supplements on their own didn't show clear gains. The results varied a lot between studies, so the supplement question stays open rather than settled.
