We know that no muscle works in isolation and the brain thinks in terms of movement, not muscles. So I think the title of these videos (and articles) may be misleading for those who are not familiar with the paradigm and principles that support it. Despite calling it QL training, you will notice very quickly that Dr. Liebenson & Chad Waterbury are training patterns and functional whole body exercises, not working to isolate an individual muscle. Keep in mind our common movement patterns as you review this and realize how neglected that lateral direction or transverse plane can be. So far today I’ve spent 95+% of my time moving forward on level surfaces. My activation of the lateral stabilizers has been minimal. Our modern society and common training exercises necessitate evaluation of this plane and likely incorporation of these exercises into most routines.
A great introduction, now see how it’s done.
Some addition reading: on Dr. Liebenson’s blog & Chad Waterbury’s blog.
Also a previous post by Dr. Cubos on Gluteus Medius activation which includes the role of the QL.
We must assess all planes and all movements. Treatment is the applied to the worst, pain-free pattern (treat the abnormal motor control that improves the mechanical sensitivity).
