In this episode, I get into all these viral “every man should be able to…” fitness challenges you see on Instagram and YouTube—the ones with the deep-voice narrator rattling off random benchmarks that aren’t age-graded, aren’t grounded in any science, and somehow declare you “top 10% of health.”

I talk about why the subject is relevant, what these lists get wrong, and how to think more clearly about real fitness benchmarks—especially as we age. I share the simple 6%-per-decade decline metric from masters track, my own goals in the 400 meters and high jump, and the example my dad set as he gracefully slowed down from walking entire golf courses in his eighties to looping the backyard in his nineties. The big point: we all slow down, but we don’t have to fall apart.

From there, I take you through the real markers that matter for longevity and everyday vitality: walking as the centerpiece of aerobic conditioning, maintaining functional muscle strength to stave off sarcopenia and “opia,” and why explosive power—being able to save yourself from a misstep—is literally a one-rep-max that can determine your fate.

We get into the dangers of falling, the massive brain-health benefits seen in active seniors, why VO₂ max is just one slice of the picture, and why the best longevity challenge of all is simply doing something you love enough to keep doing it for life. I also make the case for the 400 meters as the ultimate full-body benchmark—an event that forces you to tap every major energy system and says way more about real-world fitness than shuffling through a half marathon or throwing around big weights.

If you want a clearer blueprint for staying strong, powerful, mobile, and fully alive deep into your later decades, this one pulls all the pieces together.
