I want to push back on the "only weights or elastic bands" as tools to address sarcopenia.
My upper body (pecs, deltoids, biceps, triceps) are noticeably larger since I started rigorous swim training. And, I will never be mistaken for Arnold Schwarzenegger or Lou Ferrigno.
My quads and hamstrings are not as developed as my upper body, but doing OK imo. Undoubtedly better than if I didn't cycle or run.
I prefer objective measurements (weights, dimensions, volume) when talking about what is "good" or "better". It is too easy to drift into opinion which does not lead to understanding imo.
What about push-ups? What about sit-ups? Are they totally ineffective against sarcopenia? A little effective? A lot effective? Serious questions.
My goal is "overall health". This is all-encompassing. I am not trying to relive my 20s or to compete in body building or competitive sports.
I want to read peer-reviewed papers that describe longitudinal sarcopenia studies and measure the differences in muscle volume in response to many different forms of exercise. This is an easy scientific concept, the question is how many papers have been written like this?
