Over the years, I’ve pushed my body to the extreme—first as a competitive tennis, water polo and volleyball athlete, then a bodybuilder, then through the grueling demands of Ironman triathlons, adventure racing, obstacle course racing, and relentless biohacking experiments. Plus, I've had the privilege of helping a lot of clients – from movie stars to CEO's to mothers and fathers – lose weight and gain muscle.

So yes, I’ve spent decades dissecting fat loss, metabolism, and peak performance, blending cutting-edge science with real-world application to crack the code on burning fat, building muscle, and optimizing recovery.

And now, I’m sharing everything I’ve learned about getting lean and mean in my newly revised book, Boundless: Upgrade Your Brain, Optimize Your Body & Defy Aging—launching April 8th! To celebrate the launch, I’m giving you Chapter 8 of Boundless for free so you can get a taste of what the book has to offer and start applying these powerful principles today.

Here's what you’ll learn in “Chapter 8: Lean and Mean—How to Burn Fat Without Destroying Your Body”:

• 🔥 The real science behind fat loss and metabolism, including why the “move more, eat less” approach is incomplete.
• 🦠 Why inflammation is sabotaging your fat loss and how to shut it down.
• 💪 How to stay trim, strong, and energized year-round without starving yourself or overtraining.
• 🧬 Advanced fat loss strategies, including how to manipulate metabolism, train smarter (not harder), and use biohacks like cold therapy to crank up your metabolism and accelerate results.

My approach to getting lean isn’t about quick-fix diets or suffering through endless cardio. It’s about equipping your body with the tools it needs to burn fat efficiently, build muscle, and perform at its peak—all backed by science, personal experience, and the latest breakthroughs in health optimization.

After years of testing every biohack, training method, and performance-enhancing strategy out there – and talking to super-smart nerds for a couple hours twice a week for seventeen years for my podcast – I have realized that most mainstream advice is confusing, outdated, incomplete, or just plain wrong.

That’s exactly why I wrote the latest edition of Boundless—to create the ultimate blueprint for peak physical and mental performance, blending ancestral wisdom with the latest science to help you burn fat, build muscle, sharpen your mind, and extend longevity in a sustainable way. Consider it a complete roadmap to taking control of your health, energy, and resilience for life.

Now, you can go beyond the outdated fat-loss and wellness advice and tap into the real science of staying sharp, strong, and unstoppable.
