The principles work harder when the margin for error is thinner.<br></p><p>If you&#8217;re a clinician looking at the gap between &#8220;exercise is medicine&#8221; and what you can actually prescribe in fifteen minutes, there&#8217;s content here too.<br></p><p>Cadence: weekly posts, sometimes more when something earns it. Field-grade protocols, hard logic, real data. No theater.<br></p><p>The author writes from the trenches, not the finish line. The 320 to 206 happened. <br>The Spartan training is happening. The book is happening. Beast Logic is what&#8217;s getting written down along the way.
