Sacroiliac Joint Exercises

These 4 buttock exercises are demonstrated in this sacroiliac joint exercises video along with exercise progressions and safety tips:

1. Floor bridge


Lying down on a firm surface on your back, knees bent, feet flat and head supported


  • Push down through your heels
  • Lift your buttocks off the mat
  • Breathe out as you raise your body
  • Slowly lower your body down to starting position


Place a weight on your pelvis to load your hips

2. Clam 


Lying on a firm surface on your side, knees bent and head supported


  • Raise the top leg just above the lower leg*
  • Keep your uppermost foot resting on your lower foot throughout
  • Slowly lower the lifting leg back to starting position
  • Repeat lying on the other side

*Avoid rolling the trunk during this exercise by lifting the top leg too far from the lower leg


Position a weight on the upper outer thigh close to the knee

3. Alternate arm and leg raise


  • Lying prone with or without a pillow supporting the hips and pelvis
  • Forehead down and supported on the back of the hands


  • Gently contract the lower abdominal muscles
  • Raise one leg held straight just off the ground
  • Lower the leg back to the ground
  • Repeat on the opposite side


If the shoulders are comfortable with the arms extended out from the body, lift and lower the alternate arm and legs simultaneously

4. Heel prop


  • Lying prone with or without a pillow supporting the hips and pelvis
  • Forehead down and supported on the back of the hands


  • Bend one leg at the knee to approximately 90 degrees (right angle)
  • Lift the bent leg pushing the flexed foot towards the ceiling
  • Lower the bent leg back to starting position
  • Repeat with the other leg

Tips for Safe Sacroiliac Joint Exercises 

  • Use a small pillow or cushion to support your his and pelvis when lying prone for comfort
  • Keep the exercises small range when starting out and gradually progress according to your physical comfort
  • Cease any buttock exercises that causes SIJ discomfort
  • Avoid over bracing (tensing) your deep abdominal and pelvic floor muscles during these exercises.

The pelvic floor muscles and/or deep abdominal muscles may involuntarily spasm with SIJ pain 2. The deep abdominal muscles can be gently activated during these exercises. Aim to keep your pelvic floor muscles relaxed during these exercises.

How Many Exercises?

  • Start out doing that number of exercises that feels comfortable for your body
  • Generally aim to perform around to 10-12 repetitions of each exercise at a time (1 set)
  • Repeat up to 3 sets of exercises on one day
  • Strengthening exercises can be performed 3-5 times per week

Current Approaches to Treating Sacroiliac Joint Dysfunction

Current approaches to treating SIJ dysfunction vary from one country to another 1.

1. Exercise for SIJ Dysfunction

Sacroiliac joint exercises are used by many therapists worldwide treating sacroiliac joint problems. Exercise therapy is often used in addition to SIJ treatment techniques such as joint manipulation, massage, acupuncture, bracing and muscle stretching.

Research has shown that the buttock muscles help stabilize the SI joint 3 and the hips 4. Some studies have shown that buttock muscle activation is altered with SIJ pain 3. The buttock muscles have been shown to contribute to SIJ stability 3,4.

Training the lumbopelvic stabilizing muscles has been shown improve pain and physical disability in some individuals with chronic lower back and pelvic pain 5. Some studies show that SIJ treatment with exercises is effective while others show no benefit 6.

2. Multidimensional Management of Chronic SIJ Pain

Some researchers have recently suggested that pelvic girdle pain is not caused by joint instability or dysfunction 2.

Instead they suggest that the pelvic support structures such as the deep ligaments that support the pelvic joints become increasingly sensitive causing pain (including SIJ pain). Research has demonstrated that some women with chronic lower back and pelvic pain after pregnancy have a fear of movement, sleep deprivation and altered body image 7.

Treatment based upon this new approach involves individualized therapy that normalizes cognitive (thinking and beliefs) and function (movement patterns). Sacroiliac joint treatment strategies using this approach may include strategies such as reducing stress, addressing fears and beliefs related to moving and correcting movement patterns 2.
