I’ve had a lot of requests recently for exercises for the SI joint. I’ve been thinking of all the exercises my PT Paula gave me, as well as a few I came up with on my own.
And as I’ve been coming up with my list, it dawned on me that the most important part of all of these exercises is to be aware of the positioning of your core, and to a lesser extent, your pelvis. This is actually the most important thing to get right, before you start progressing to other forms of exercise.
So in this post, we’re going to talk about how to to strengthen your core muscles, and in particular, a muscle called the transverse abdominis.
The transverse abdominis is the #1 most important muscle to strengthen to stabilize the sacroiliac joint. As you can see here, it wraps around the whole front of your torso. When you tighten it, it’s like tightening a corset.
I consciously remember my TA at times when my SI joints are hurting, and I’m having trouble making it from Point A to Point B. I think “oh wait– I have this amazing muscle that can help!” Then I contract the TA, and it almost feels as though someone or something is giving me a gentle hug in the front of my body, helping to hold me up.
Although this muscle is in the front of the body, it actually helps to support your whole spine. When it’s working, the difference is night and day.
The tricky thing about the TA is it’s not the most straightforward thing to learn to identify. As the guy in this video says above, it’s not like strengthening a muscle like the bicep, where you are looking to create a lot of force.
In the beginning, for most people, learning to identify the TA and contract it at all counts as “exercise.” Because it’s not so much about creating brute strength as it is becoming consciously aware of that muscle, and learning how to contract it when you really need it.
Technically, as part of the core, the TA is working on some level all of the time, without your conscious awareness. However, studies have shown that, in people with back pain, the relationship between the brain and the TA can be disrupted, and the TA tends to be weak. So training it has a lot to do with cuing your brain in to use this muscle again.
Below is an example of a physical therapist showing a patient how to contract the TA. You will see that, at the 45 second mark, there are two main instructions that he gives:
- To draw the belly button down to the spine.
- To gently rock the pelvis backward, “like you’re curling up your spine.” This is what’s known as a posterior pelvic tilt.
Technically, to contract the TA, all you really need to do is the first part, “belly button to spine.” This is what I focus on when I’m standing up right and walking around, and just need a little more support.
However the second part, about the posterior pelvic tilt, ensures a stronger TA contraction, and it’s also a really great way to help protect your lower back during certain exercises.
For example, a very common way to start out strengthening the core is to do exercises such as the one below, where you are lying on your back and contracting the TA:
Often, when your core muscles are weak, your body will try to compensate by arching your back. This puts unhealthy stress on your lower back (I actually start to feel pain when I do it, which is a great way to know when I don’t have proper form!).
So, having this slight posterior pelvic tilt helps to get a fuller contraction out of the TA, and also ensures that you are protecting your spine.
Obviously, it will not be possible to have a posterior pelvic tilt during all of the exercises you do, but at times when it is possible (such as these lying down exercises), it makes all the difference.
I know this is a complicated subject.
I know people are really excited to get information on SI joint exercises, so I really wanted to get something out to you.
The truth is, however, that I honestly wouldn’t expect you to be able to master TA contractions based on Youtube videos alone.
I really, really recommend that you work with a qualified physical therapist. I honestly think that’s the only way to go. (While doing my research for this post, I found a bunch of scarily wrong videos and articles from personal trainers! I do have two on here from personal trainers, but I made sure that all of their information is correct).
Honestly, it took me a while to learn to contract the TA. I definitely did not get it on the first try, like the “patients” in these videos (who might actually be PT’s themselves). It’s somewhat of an art form, especially learning to contract it without also holding your breath.
But you can eventually get there. After all, it’s something your body is meant to do, and it’s a very powerful tool that’s there for you to use. You just have to trust that you can figure it out, and keep going. Once you feel it, you’ll know.
