The MOST Important Hormone for NATURAL Muscle Growth!

Most natural bodybuilders are obsessed with testosterone and growth hormone for muscle growth, especially men over 40— and that obsession is holding them back.

In this video, I break down the single most important driver for building muscle as a natural athlete, and it’s not a hormone, supplement, or hack and why the ide of trying to increase testosterone naturally, is a fundamentally bad idea.

After more than 34 years of natural training, going from 125 lbs at 6 feet tall to becoming a natural bodybuilding champion and still maintaining a great natural physique at 51 years old, I can tell you this with certainty:

👉 Muscle growth is driven by a process — not a chemical.

In this video I go over:

Why testosterone and growth hormone are not the primary drivers of muscle growth

The hard hormonal ceiling natural athletes must respect

How the General Adaptation Syndrome (GAS) actually governs muscle growth

Why recovery — not training volume — determines your results

How brutally intense, low-volume training combined with adequate rest produces superior gains

Why training more days per week often leads to less muscle for natural lifters

If you’re over 30, over 40, over 50 or over 60 or training naturally at any age, this video will completely reframe how you think about muscle growth and natural bodybuilding and show you how to train smarter, not longer.

These principles are the foundation of Naturally Intense High Intensity Training — a science based high intensity training system built around stimulus, recovery, and adaptation, and not hormone chasing.

I hope this video helps give you some perspective on what you really need to focus on if you want to build muscle naturally and I hope it helps you on your path to excellence! Thanks for watching and as always, Excelsior!!! #naturallyintense
