I love aging research that blows apart the zeitgeist of “normal” aging. I’ve presented on it 2 different times and my graduate work was built around how strength training improves cognitive function in aged populations. I love this stuff.
The videos are available on youtube, but if you’re not interested in sitting through a video, I made an ebook version that covers what I feel are the greatest hits, the things that are the most compelling evidence for strength training as the closest thing we have to a “fountain of youth.” I’ve worked hard to make it an easy read without watering it down.

Strength training IS the fountain of youth,especially moderately heavy,safely done compound movements! Sadly,many have bought into wussified,non-productive activities
