This is a book about breathing biohacking - a system for consciously directing your own energy through the one tool that's always with you: your breath.Your personal energy depends on billions of tiny power stations at work inside the cells of your body. These are your mitochondria. It's here that most of your body's energy is produced, in the form of ATP molecules.It seems impossible to influence this process directly. Breathing biohacking proves otherwise. Take conscious control of your breath, and you can literally hack the way your mitochondria work - and rev up your own energy output. These conscious breathing techniques work at the molecular level.This isn't abstract theory - it's a working practice. A practice that trains your mitochondria and raises your energy output. This is how an entirely new kind of fitness emerges: breathing fitness. You're not training your muscles. You're training your mitochondria.Inside this book: breathing techniques, a complete breathing fitness system, the Biohack Lite and Biohack MAX programs, and specialized protocols for physical performance and deep recovery.Your breath is one of the most powerful biohacking tools you've always owned but never truly switched on. It's time to turn it on.
