008: The Science of Freediving: Hold Your Breath and Extend your Lifespan

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!

Episode Highlights:

  • 00:58 – Why I freedive
  • 05:50 – Cryotherapy or cold exposure therapy to find calmness
  • 07:02 – The benefits of diaphragmatic, nasal, and box breathing
  • 10:15 – “The best training for any kind of sport is going to be that which closely mimics the sport itself.”
  • 12:12 – VO₂ max = cardiac output * A-VO₂ difference
  • 15:12 – Why high-level divers do HIIT and blood flow restriction training
  • 16:48 – How to estimate your maximum heart rate
  • 17:18 – How to increase your oxygen-carrying capacity
  • 19:21 – On carbon fiber fins and low-volume masks
  • 22:00 – Divers would benefit from more BCAAs, electrolytes and carbs

007: Seaweed, Spearfishing, and Sustainability with Kabir Parker

Our guest for today is Kabir Parker—marine biologist, University of Miami graduate, master freediver, and conscious spearfisherman. After realizing that doing scientific research alone is like diagnosing a problem but not fixing it, he decided to take a more active role to protect the oceans and marine life through entrepreneurship. Through his Instagram and Youtube, he educates people while taking them on diving and spearfishing adventures.

In this episode, Kabir and Andres dive into some of the research that Kabir is involved in. They also share freediving and spearfishing techniques that can also be used for stress management and relaxation. Finally, Kabir presents a sustainable approach to eating seafood and offers tips on choosing reef-safe sunscreen so that people can lower their carbon footprint.

Episode Highlights:

  • 04:00 – Kabir’s venture into seaweed agriculture
  • 06:13 – Okeanos®, developer of Made From Stone™
  • 08:10 – On making a significant positive impact on the ocean
  • 09:21 – Why he became a marine biologist
  • 13:30 – Meditation as a tool for freediving and spearfishing
  • 18:21 – America’s approach to sustainable seafood
  • 21:00 – Best options for reef-safe sunscreen
  • 23:55 – Kabir’s advice to aspiring marine biologists
  • 25:20 – Kabir and Andres’ experience spearfishing in the Bahamas
