In 1990, researchers proved something about aging that most people still don't know. It was one of my favorite studies. 10 residents, average age of 90, the oldest was 96. They had about 4 or 5 chronic diseases each. 8 of the 10 had fallen before, 7 were using a walking aid like a cane, and for 8 weeks they trained their legs 3 times a week. It was one simple supervised exercise, leg extensions on a machine for about 80% of their one rep max.
And in the 9 who finished, their leg strength nearly tripled on average. Every one of them got stronger. 2 stopped using their canes. Their thigh muscles got 9% bigger on average. They had no heart problems, no falls.
And then a bigger trial checked it with a control group. It was 100 residents and the average age was 87, and again, strength nearly doubled.
Then the first group stopped training, and 4 weeks later they'd lost about a third of what they'd gained. Which means they were still nearly twice as strong as when they started.
So we need to quit with all the ageism. The problem is not too old. The problem is too sedentary. So send this to your friend who's always using age as an excuse, and follow for more.
From the final approved script. The video may differ by a word or two.
