IIn this solo Thanksgiving re-release, Josh revisits Exercised by Harvard professor Daniel Lieberman—a fascinating look at the science of physical activity, rest, and health. As many people slow down for the holiday, Josh offers a thoughtful reminder that movement doesn’t need to be extreme to be meaningful. Using his Readwise app, he walks listeners through key highlights from the book, why humans evolved to conserve energy, and how our modern relationship with exercise often conflicts with the biology we inherited.
From post-meal walks after a big Thanksgiving plate to debunking familiar fitness myths, this episode brings practical insights and a timely nudge toward simple, sustainable movement.
Before diving in, Josh shares a quick note of gratitude for everyone who listens, supports, and shares the show. This community continues to grow because of you.
