Kyle Kingsbury is the Director of Human Optimization at Onnit, a retired mixed martial artist and UFC fighter, and the host of the Kyle Kingsbury Podcast—which helps listeners achieve peak performance in everyday life by sharing fitness regimens and mindsets of the brightest minds and strongest athletes in the world. Kyle is a living example of how diet, nutrition, training, plant medicine, and technology can be harnessed for optimal cognitive and physical power.

  • The tricks and tactics Kyle uses to foster a better mind and body connection.

  • The benefits of cold and heat stress (and how to reap these benefits even if you don't have access to a sauna or cold plunge).

  • Kyle's top hacks for better sleep—and his favorite sleep tracking device.

  • Why Kyle defaults to a ketogenic diet.

  • Kyle's intuitive training program that keeps him in killer shape without the "bro split" that's often recommended in fitness circles.
