Looking For Stretches For Your SI Joint?
Stretching your SI joint is actually a BAD idea. The SI joint isn't designed to move much. However, stretching and strengthening exercises for the back and hip muscles can help if you have SI joint pain.
Watch the video to learn the best stretches for SI joint pain, plus exercises to stabilize the SI joint.
Stretches For SI Joint - Good or Bad?
Your SI joint, or sacroiliac joint, is a an expansion joint between your lower spine (sacrum) and your pelvic bone (ilium).
The bony configuration of the SI joints along with very strong, stiff SI ligaments makes the SI joints very stable.
The joints normally only move 1-3 milliammeters or rotate 1-3 degrees during movement.
Basically they are designed to help transfer loads from the legs to the spine as you move. The SI joints are NOT designed to move like a knee joint, elbow joint, or hip (ball-and-socket) joint.
When the aforementioned SI ligaments get stretched out, that can create hypermobility - too much movement - in the joint.
Hypermobile SI joints are often the cause of chronic SI joint pain.
Therefore, it's NOT a good idea to stretch the SI joints themselves.
You don't want to create hypermobility.
What Can Cause An Over-Stretched SI Joint?
SI joint hypermobility can be caused by:
- Hormonal changes in women, particularly during pregnancy
- Congenital hypermobility such as Ehlers-Danlos Syndrome.
- Trauma, such as a car accident or fall on one leg
- Twisting injuries to the lower back
- Repetitive activities with asymmetrical forces on the right and left leg
What About A Stuck SI Joint or Locked Up SI Joint?
As previously mentioned, a normal SI joint doesn't move very much to begin with. So a stuck or locked up SI joint has almost NO movement.
SI joints that are hypermobile have a tendency to get "stuck" in an end-range lock position, where they are temporarily stiff or hypomobile (move too little).
A locked up SI joint can be incredibly painful and keep you from walking or standing up from a chair comfortably.
However, a locked up SI joint is really just a stuck hypermobile joint.
You need to get the joint unlocked, and spinal manipulation is a very effective treatment to unlock a stuck SI joint. As manual physical therapists, we use spinal manipulation quite often, but we also recognize when it's more appropriate to use other treatments instead.
Ultimately though, after you get a stuck SI joint unlocked, it returns to it's hypermobile state. That means the long-term solution is still stabilizing the hypermobile SI joint so that it doesn't keep getting locked in the future.
Stretches For SI Joint Pain Relief
Hopefully I've made a compelling case for why you DON'T want to stretch your SI joint itself.
That being said, stretching the muscles AROUND the SI joint can be helpful for SI joint pain relief.
Muscle imbalances can contribute to SI joint pain. Some examples of these imbalances include:
- Front vs. back muscle imbalances
- Side to side muscle imbalances
- Diagonal muscle imbalances
Mostly, these imbalances involve your lower back, abdominal, and hip muscles. Below are some stretches for SI joint pain relief that target these muscles.
The child's pose is one of the best exercises to relieve lower back pain.
To do the child's pose, you kneel on all fours and rock your hips back toward your heels.
One of the reason child's pose such a great stretch for SI joint pain is that it allows you to stretch muscles both above and below the SI joints.
You can stretch the lower back muscles by letting your back round as shown in in the picture above. Alternatively, you can stretch the back of the hip muscles by keeping an arch in your lower back as shown below.
Hip Flexor Stretches
Hip flexor stretches are also great for SI joint pain as well as lower back pain.
Whereas the psoas muscle usually has the greatest effect on lower back pain, the iliacus, rectus femoris, and tensor fascia latae muscles usually have the greatest effect on sacroiliac joint pain due to their direct attachment on the ilium.
Most people think they have stiff hamstrings. In reality, most people aren't as stiff in their hamstrings as they think.
Doing a typical "hamstring stretch" does put your sciatica nerve on tension, so often people feel stiff or tight.
Some people DO in fact have stiff hamstrings though. If you lay on your back and you can't lift your leg up straight to almost 90 degrees (80 is normal), you may have stiff hamstrings.
Since your hamstrings attach to the back of your pelvis (ischium), they can affect your SI joint.
Your piriformis muscle runs from your sacrum to your hip thigh bone (femur) without a direct attachment to the ilium.
That means an imbalance between the left and right piriformis muscles can cause your sacrum to twist between the ilia. In turn, this sacral torsion can cause SI joint pain.
Remember you want to stretch the muscles AROUND the SI joint.
You DON'T want to stretch the SI joint itself!
What Are Other SI Joint Exercises For Pain Relief?
As previously mentioned, the most important long-term solution for SI joint pain is stabilizing the joint so that it doesn't keep locking up.
If your SI joint ligaments have become overstretched, stabilization comes by way of strengthening the muscles around the joint. Here are some strengthening exercises for SI joint pain relief.
Abdominal Strengthening Exercises
The deep abdominal muscles, namely your transverse abdominis is one of the main stabilizing muscles of the SI joint.
As the name suggests, it runs transversely (side-to-side) between the two ilia.
Pulling your belly in as if trying to fit into a tight pair of pants and slightly tilting your pelvis is one way to strengthen the transverse abdominis.
You don't necessarily need to "make time" to do this exercise either. You can do it pretty much anywhere at any time.
And the more often you do it during the course of your day, the easier it gets and the sooner you'll likely start feeling better.
This is also a very important exercise to do if your lower back hurts from standing too long.
Glute Strengthening Exercises
Strengthening your glute muscles, and particularly your gluteus maximus (butt) muscles is also an important type of exercise for SI joint pain relief.
The gluteus maximus is really the only muscle that directly connects to BOTH the sacrum and the ilium, so it's important not to neglect your glutes.
Squats and leg presses are great exercises for your glutes, as are lunges.
However, if your SI problem is really irritable, you may want to avoid lunges initially because it puts your legs in an asymmetrical position which can cause your SI joints to rotate.
Once you've gotten over the acute phase though, lunges are a great exercise to prevent a recurrence of SI joint pain because they work each side of the glutes independently of the other.
Lat Strengthening Exercises
Your latissimus dorsi (a.k.a "lats") on one side of the body connect with the glutes on the opposite side of the body through the thoracolumbar fascia as shown below.
When both muscles contract at the same time, they stabilize the SI joint diagonally.
Pullups or lat pulldowns are good exercises to strengthen the lats.

Do SI Joint Belts Help?
SI belts do often help if you have a hypermobile SI joint.
SI belts are worn around your pelvis to compress the SI joints and make them stable.
There are some downsides to SI belts though:
They're not particularly comfortable.
It's hard to sit down in them.
Take home point on SI belts:
They're good for short-term relief when being active, but you shouldn't wear them all the time. They're also not an optimal long-term solution.
What Other Treatments Can Help SI Joint Pain?
As previously mentioned, spinal manipulation is very effective for actue SI joint problems when the joint gets locked or stuck.
Most importantly, learning how to move properly during daily activities can help prevent your SI joint pain from coming back. Some of these activities include:
