Episode 432: Kris Gethin: The Natural Blueprint for Building Muscle After 40

Habits and Hustle

Can you build muscle naturally as you age?

In this week’s Fitness Friday episode, I talk with fitness expert Kris Gethin, as he reveals that declining testosterone may be the hidden culprit behind your struggle to maintain muscle mass after 40. Most middle-aged fitness enthusiasts who maintain impressive physiques rely heavily on hormone replacement therapy (HRT), but Kris shares a completely natural approach that works.

We discuss surprising testosterone-killers lurking in your daily environment—from cooking with Teflon to the metal fillings in your teeth—and provide practical, scientifically-backed strategies to boost your hormone production naturally. We also dive into cutting-edge biohacking techniques like red light therapy, ice baths, and even how dental work dramatically improved Kris's own hormone levels after suffering from long COVID.

Kris Gethin, a renowned transformation expert and entrepreneur, has revolutionized the fitness industry with his no-nonsense, results-driven approach to bodybuilding and coaching. As the founder of Unmatched Supps and former CEO of Kaged Muscle, he has established himself as a pioneering force in the supplement industry while developing the innovative DTP (Dramatic Transformation Principle) training method. Through his podcast, he shares evidence-based fitness insights with a global audience, drawing from his extensive experience coaching elite athletes and celebrities.

What we discuss:

• Natural testosterone optimization vs. HRT dependency
• Environmental testosterone killers
• Compound exercises that stimulate hormone production
• Red light therapy benefits and application techniques
• How ice baths and saunas can elevate testosterone levels
• Unexpected connection between dental health and hormone production
• Natural alternatives to Ozempic and GLP-1 medications for fat loss
• Supplements that support testosterone (vitamin D with K2, creatine, progesterone, DHEA)
• Blood sugar stabilization techniques for maintaining muscle and losing fat
