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
