Muscle, Power, and the Real Cause of Age-Related Decline

In this video, I break down the groundbreaking April 2025 study that followed elite sprinters for 10 years — and reveals what really fails with age: not the muscle, but the signal.

I expose why fast-twitch fiber programs, sprinting routines, and one-dimensional sports fail you after 70…
I explain why rate of force development (RFD) is the real biomarker of youth…
And I lay out the truth behind neuromuscular decline, chaos training, and the closed-loop somatic system no one talks about.

This isn’t theory. This is reality, backed by science, lived by me.

Disclaimer:

This video is not medical advice. I'm not telling you to stop sprinting — I’m telling you the truth:
Sprinting alone won’t save you. Chaos training. Unpredictable stimulus. Neurological preservation.
That’s what keeps your nervous system alive. If you’re still chasing traditional training at 70, 80, or 90 — You’ve already lost the race.
