Sitting Perfectly Still Only Time Humans Don't Use Large Muscles, Causes Health Crisis

What was said

"It's not actually sitting that's problematic. It's sitting still. When you sit perfectly still, it's the only time in your life pretty much when you're not using your large muscles at all. And that's what's causing a lot of these problems. That's what's causing the vast majority of these health problems aside from the musculoskeletal issues."

King challenged the conventional wisdom that sitting itself is harmful, arguing instead that sitting perfectly still is the real culprit. He explained that static sitting is the only time in human life when large muscles remain completely disengaged, even compared to sleeping when people naturally move. This lack of muscle engagement drives both musculoskeletal and broader health problems.
