Great article.
I attempted to have a conversation about this with an older relative. A little over 70. I've noticed his slow decline. He is physically active, but pretty weak buy most metrics and only getting more so. Really, I knew the conversation would not go anywhere but I just found myself not able to not say something. Here was his response to adding some weight to his routine.
"I don't increase the 8 and 20 lb dumb bell weights, but I do try to do them faster, which I suspect is equivalent. My regular exercise is a base which I supplement with chores such as clipping vegetation back from the drive and a wheelchair in and out of the car. Also the occasional case of paper, or 24-bottle packs of water. I also try to eat healthy, with a number of supplements like Vitamin D, Iodine, and probiotics. And I maintain my weight at my college level of 145 pounds; that is perhaps my most challenging discipline. I make sure to get enough sleep. Living healthy is my lifestyle. But age looms regardless."
I guess I know he is set in his ways and won't change what he has always done. And to his credit, he is active. But minor falls are happening on his thrice weekly 1.3 mile run. His response is to slow down. That just feels so wrong.
I was hoping the article would address that doing the same non-taxing thing over and over (8 and 20 lb weights) won't preserve muscle mass and bone density. Is there an article here that addresses that specifically? I find the comment here in there but nothing specific.
