In this video I discuss the implications of anterior pelvic shifting opposed to anterior pelvic tilting. Elaborating further on the common problems found from people who have tight hip flexors and subsequently have low back pain.

The path towards finding out what efficient movement is for a human being has been one of great difficulty considering all the variables that are thrown my way when I experiment in the lab.

I have found that much of what has been written in textbooks regarding biomechanics definitely have validity, but only within a very limited context.

So much of the information found in books claiming to address muscular imbalance have seemingly failed at some of the most basic principles of kinesiology.

In the video above I break down what an anterior pelvic tilt actually looks like and how it applies in reality.

Although it’s a bit different than the explanation of what I’ve seen others use to describe lumbo-pelvic hip imbalances, it seems to pin down what is actually going on in the body when deficiency is present in that region.

I find that most theory out there is next to useless and hopefully people will be able to find use from videos like this and ones I will be posting soon similar.



Hey guys, this is Naudi Aguilar at Functional Patterns, and for today’s video I’m going to be discussing the Lumbopelvic Hip Complex Efficiency. Awhile back, while making a video talking in regards to Anterior Pelvic Tilts and the commonality that I find in them, and subsequently how often people have lower back problems directly related to those inefficiencies built in those neuro structures. What I want to do in this video is to elaborate on that a little further and bring a new idea to it, where I don’t really talk about so much of an Anterior Pelvic Tilt per se, but more of an Anterior Pelvic Shift. I’m going to explain this as we go along for this video.

For starters, what I had discussed before was that when somebody is sitting down over the course of several hours throughout the day, the brain is going to make adductions to this specific environment. The human being itself has been adapting into an environment where movement was involved and we were doing a lot of bipedal movement on two feet. Over the course of million years, the human body got very good at that. With industrial revolution coming through together in our culture, things changed dramatically and we have found ourselves sitting down for several hours a day for decades at a time. What the problem is with that is that the brain ends up wiring in the patterns that we create here, and specifically what I want you guys to think about is more the specific context of where the body is operating from. I’m going to give you guys a reference point of how to really measure efficiency with the human body.

If you guys look into really good textbooks that discuss how muscles work, you’re always going to tend to find a rank body action that goes along for each muscle. You’ll have a first rank, let’s say for the gluteus maximus, in this situation, the first rank is going to be called hip extension where you’re going from the front to the center line, then we’re going to have hyperextension and then as a third function we will have external rotation. How is this important for us specifically in this context? Well, when the brain begins to wire in the deficiencies of sitting down over the course of a long term, we have to think that we’re going to begin to develop neurological connections while we’re making these adductions that wire in hip flexion. We then build fascia associations along with that, where the fascia gets really, really tight. When we stand up, we’re going to then shut the initiation of hip extension going from here all the way to the center line. That’s our primary function.

If the primary function is knocked off, well then we’re going to have to rely beyond that it’s going to be a hip hyperextension, where we’re going from the center line all the way back. What’s that going to look like when we stand up? Where we end up shifting the pelvis anteriorly and that’s what I’m speaking in regards. Rather than talking about an Anterior Pelvic Tilt where we’re going here just tilting the pelvis, I call it more of an Anterior Pelvic Shift. Since we have shut down the hip extension from being at a desk for so long, what the brain does is it bypasses hip extension it goes straight to hyperextension. As a result of that we end up getting this force coming forward, and that’s where we end up getting a lot of the pressure happening in the glutes. Accompanying that, we’re also going to find a hip external rotation because that’s going to be typically the third function of the gluteus maximus.

Hopefully that’s going to add some clarity in terms of what an Anterior Pelvic Tilt is, and that really an Anterior Pelvic Tilt is a significant outcome that happens as a result of sitting down and having tight hip flexors, but it’s not the most applicable one. Very few people stand like this, and oftentimes when you look at people that have, let’s say they have kyphosis, people will say that if somebody has kypholordosis to try and almost, I’ve seen experts that describe it as where you have a curve here and then you’re round here. I, myself, have never seen anybody walk like that. Typically, what I end up finding instead is that when people end up having the hyperextension of the pelvis that things shift anteriorly in the pelvis, and then the upper body drops froward as a form of compensation. This is typically what we’re going to find out of most people’s posture.

As I mentioned prior, in the last Anterior Pelvic Tilt video, you’re going to end up finding poor gluteal function in terms of hip extension, beyond that we’re going to end up finding a lot of weak lower abdominals, then we’re going to have tight upper abdominals pulling the thoracic spine forward, subsequently bringing about a forward head, and then with that we’re going to have pressure in the lower back from there. There’s going to be, this is the base dysfunction that I want you guys thinking about when somebody has an imbalanced posture. What I’m going to be trying to do in the next coming videos, for the next few weeks is take you from transitioning from here all the way to here. Now, I’m going to be releasing things little by little because there’s a lot to cover. If you do want more information directly on how to address this, and learn the science behind how to actually fix these problems of working on secondary functions, they can be found in my Power Posture book, or in my Human Foundations series.

And all the videos I cover, they directly help with addressing these specific problems and I help teach you the science of how to address these issues at their core. Because these things are very complex, there’s not going to be one magic solution because when you change an association here, that goes up the kinetic chain and then when you start walking and things go all over the place, and then it becomes a process of trying to find out the root behavior, what’s going wrong. And then you see that it’s just an entangled web of, an entangled mess that’s holding you back from moving into your full potential. I do hope that you guys found this video to be useful, and that it added clarity in terms of how your bodies likely functioning right now based on how you’ve made adductions to this stationary environment.

I do invite you guys to check out my website at because there’s a lot of information that directly covers this. You can also subscribe to my YouTube channel so you can continually get updates on future videos that I will be putting up. This is Naudi Aguilar, reminding you to think intentionally, and not habitually. Take care.
