You probably already know that I’m an exercise physiologist—and I’m currently pursuing a master’s degree in applied physiology with a concentration in nutrition for health and human performance—but I’m also a freediver and a spearfisherman. Anybody can freedive but I help people take it to the next level by biohacking their lifestyle.
Have a pen and paper ready because, in this episode, I dive deep (pun intended) into the physiology of elite-level freediving. From breathwork to training, I break down a bunch of techniques so that you can dive deeper and hold your breath longer. I also dish out tips on diving gear and nutritional supplements so stay tuned until the end!
