Boundless is for anyone seeking optimized cognition, upgraded energy, enhanced performance, better recovery, and even more happiness, meaning and purpose.

Let’s face it: we health seekers face an uphill, frustrating battle of confusing and contradictory wellness advice from books, blogs and podcasts, complex nutrition recommendations that seem to change every single day, a never-ending flurry of perplexing information about what workout, diet and lifestyle is perfect for you and a dizzying new realm of biohacks, supplements, medication, anti-aging strategies and much more.

Yet despite all this information, perhaps your body and brain still don’t feel right. Afternoon brain fog frequently sets in, your gut rumbles with mild, distracting bloating, and you just can’t seem to gain that muscle, lose that fat and get that body you want. You still feel like something is missing—the blueprint to feel the true energy every human being should have. But things don’t need to be this way.

This book is for high achievers who want to live, eat, breathe, and vibrate in a truly superhuman way, every hour, every minute and every second of every day.

Boundless gives you every last tool you need to build your best life and unlock true, lasting energy forever.
