Mike McCastle smashed David Goggins' pullup record by doing 5,804 pull-ups in 24 hours while wearing a 30-pound backpack... and pulled an F-150 pickup truck 22 miles through Death Valley... and flipped a 250 lb tire for 13 miles... and climbed a rope for the equivalent distance of Mount Everest... and has trained MMA fighters, alpinists, and extreme adventurers like Colin O'Brady, the first man to cross Antarctica solo and unsupported.   As such, he's the perfect person to kick off our 4-part series on hybrid training, where we'll delve into the art and science of maximising strength AND endurance at the same time.

It started as an April Fool's joke and then morphed into a BEAST of a book complete with 967 illustrations called "Brazilian Jiu-Jitsu, the Ultimate Illustrated Guidebook".  In episode 424 I chat with renowned BJJ black belt, illustrator and designer Seymour Yang (better known as Meerkatsu) and his partner in crime Graham Barlow (the creator of the Tai Chi Notebook) about the core techniques of BJJ, modern vs traditional jiu-jitsu, and the process of bringing a new book into the world.

422 - How to Condition Yourself to Deal with Adrenaline in Stressful Situations

The fight-or-flight reflex is always lurking just below the surface. When things get sufficiently stressful, our hormonal system dumps enormous amounts of adrenaline into our bloodstream, and—BOOM—suddenly we’re ready for action. That adrenaline serves a purpose: it elevates your heart rate, makes you much stronger, more pain tolerant, and able to ignore injury. If you ever have to lift a car off a child, you don’t want to be calm. Instead, you want to be mad, scared, enraged—whatever it takes to get into that adrenaline-soaked state of high arousal to lift the damn car with your bare hands. But that superhuman strength comes at a cost; as adrenaline floods your system, you lose a significant amount of fine motor control and higher brain function. Take whatever IQ you started with and cut it in half. This episode of The Strenuous Life Podcast is an excerpt from the audiobook version of Perseverance, Life and Death in the Subarctic which you can check out anywhere you get books including the links below: AMAZON: https://www.amazon.com/Perseverance-Death-Subarctic-Stephan-Kesting/dp/1639368612/ BARNES AND NOBLE: https://www.barnesandnoble.com/w/perseverance-stephan-kesting/1145682384 INDIGO: https://www.indigo.ca/en-ca/perseverance-life-and-death-in-the-subarctic/9781639368617.html Good luck with your training and all your endeavors Stephan Kesting
