Watch any sports game or step into any gym and you will see a knee buckling in. This is surprising, as inward knee movement is seen as one of the holy grails of lower body physical therapy. In fact, it is directly connected to an Anterior Cruciate Ligament tear (ACL tear), the most extensively researched leg injury.
Medical practitioners refer to inward knee motion as knee valgus and hold the glutes accountable for not being able to keep the knee out. The link between valgus and weak glutes is not just a perception, it is an amendment. It is about as plain as the nose on your face, no questions asked.
And yet, it is entirely wrong…
This knee valgus bible gets rid of the fundamental misconceptions about knee valgus. Every physical therapist, physical therapy student, personal trainer, strength coach, fitness enthusiast or movement specialist should be familiar with the pioneering knowledge inside this book.
“Why Your Knee Caves In” will throw your entire understanding of inward knee movement upside down, in a highly digestible fashion with witty one-liners and fantastic visuals. Step by step, all the cards will be laid on the table and every detail will be meticulously explained.
A masterpiece for the ages.
