🦵 Knee cartilage lacks blood vessels—and it's nourished in a completely different way than you might think. In this lecture, we'll explore one of the most underrated mechanisms in body biomechanics: how synovial fluid delivers nourishment to cartilage and why it literally starves without movement.

💧 You'll learn why cartilage is structured like a sponge, how the "pump" of compression and extension works, and why a full range of motion nourishes areas of the joint that otherwise would never receive nourishment.

🏋️ We'll also address the main myth: "deep squats ruin your knees." We'll look at weightlifters and entire cultures that live in squats, and explain why it's not depth that's dangerous, but immobility and sudden stress on unprepared tissue.

✅ The practical part includes a step-by-step, safe progression: supported squats, ankle mobility work, the "range of motion is more important than weight" principle, and consistency instead of strain. There are also tips for those whose knees are no longer ideal.

After this video, you'll look at your knees differently. 👇 Subscribe to the channel and let us know in the comments how often you squat on a typical day!
