Look around you. The average human wanders through life with brain fog, bloating, indigestion, constipation, crunching joints, insomnia, lost libido, anger, fear and a constant search for meaning. But what if this doesn’t have to be?

What if you could leap out of bed each morning and tackle the day with the extreme ferocity of an excited tiger?

“No one explores the world of health and wellness as completely and aggressively as Ben Greenfield. Ben has always been willing to go to the edges and beyond to discover new ways in which to optimize our bodies, our minds and our spirits. He delights in describing these “forays to the fringe” to his growing audience in easy-to-comprehend terms with science-based take-it-or-leave-it nuggets.”

The dude lives life in the trenches, and somehow manages to blend a perfect combination of ancestral living and modern science in a way that anybody can grasp. When it comes to getting a better body and brain, there's nobody that does what he can do, period.”

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.
