SI Joint Pain Exercises: Gentle Moves for Women

SI joint pain exercises are gentle moves that steady the joint where your spine meets your pelvis. The best place to start is a mix of glute bridges, pelvic tilts and a knee to chest stretch, 2 sets of 8 to 10 reps or 30 second holds, once a day, staying in a pain-free range.

As a NASM corrective exercise specialist, I spend a lot of time helping women sort out that nagging ache low in the back, just off to one side of the spine. Very often it traces back to the SI joint and the muscles that are supposed to support it.

The encouraging part is that this joint usually responds well to steady, simple work. Below you’ll find what the SI joint does, the safest stretches, the strength moves that matter most, standing and senior-friendly options, and the signs that mean you should get checked instead.

What the SI Joint Is and Why IT Hurts

You have two sacroiliac (SI) joints, one on each side, where the triangle-shaped bone at the base of your spine (the sacrum) meets the wings of your pelvis. You can often find them under the two small dimples just above your buttocks.

These joints move only a few degrees. Their real job is to pass the load from your upper body into your legs when you walk, climb stairs or stand on one foot. Strong ligaments hold them together, and the glutes, deep core and back muscles help keep them steady.

SI joint pain usually shows up as a dull or sharp ache on one side of the low back or upper buttock. It may travel into the hip, groin or back of the thigh, but it rarely goes below the knee. Many women notice it most when rolling over in bed, getting out of the car, climbing stairs or standing on one leg to pull on pants.

Common triggers include a jump in activity, long hours sitting, uneven loading like always carrying a heavy bag on one shoulder or standing with your weight on one hip, weak glutes, and arthritis in the joint. Hormone shifts can also change how ligaments feel, which is one reason many women notice SI joint pain more at certain stages of life.

How to Do SI Joint Pain Exercises Safely

A few rules make SI joint pain exercises more effective and much less likely to stir things up.

1. Start small. Use the smallest range that feels comfortable and add range over a week or two.
2. Rate the pain. On a 0 to 10 scale, staying at 2 or 3 during and after is usually fine. If the joint feels worse the next morning, do less.
3. Breathe out on the effort. Gently draw your belly button toward your spine as you exhale. This light brace helps steady the pelvis.
4. Move both sides evenly. Avoid deep lunges, single leg jumps or big twists while the joint is sore.
5. Stop if it zings. Burning, tingling or numbness down the leg is a reason to stop and get checked.

Gentle SI Joint Stretches

These stretches ease the muscles around the joint rather than forcing the joint itself. Hold each one for 20 to 30 seconds, 2 or 3 times per side.

1. Single Knee to Chest

Lie on your back with both knees bent. Bring your right knee toward your chest and hold behind the thigh with both hands. Keep the other foot on the floor. Hold 30 seconds and switch.

If bending one knee feels better than two, stay with this version. Hugging both knees at once can tug harder on the low back.

2. Pelvic Tilts

Lie on your back with knees bent and feet flat. Gently flatten your low back into the floor by tilting your pelvis, then return to a small arch. Move slowly for 10 to 12 reps.

This is less a stretch than a way to remind the area that it can move. Many women find it calms a stiff, achy back in the morning.

3. Gentle Lower Trunk Rotation

Lie on your back with knees bent and together. Let both knees sway a short way to the right, then back through the middle and to the left. Keep your shoulders down and the movement small. Do 10 slow sways.

4. Hip Flexor Stretch

Kneel on a cushion with your right knee down and your left foot in front. Tuck your tailbone slightly and shift forward until you feel a stretch in the front of your right hip. Hold 30 seconds and switch.

Tight hip flexors can tug the pelvis forward, which some people feel near the SI joint. If kneeling is hard on your knees, do it standing with one foot on a step. A few piriformis stretches can also help if the ache sits deeper in the buttock.

SI Joint Strengthening Exercises

This is the part I care most about as a corrective exercise specialist. When the glutes and deep core do their job, the SI joint has much less strain to absorb. Do these 3 days a week, 2 sets of 8 to 12 reps.

5. Glute Bridge

Lie on your back with knees bent and feet hip width apart. Exhale, press through your heels and lift your hips until your body forms a line from shoulders to knees. Pause 2 seconds and lower slowly.

Keep the lift small at first if your back arches. My guide to glute bridge variations shows how to make it easier or harder as you improve.

6. Adductor Squeeze

Lie on your back with knees bent and a folded pillow or rolled towel between your knees. Squeeze the pillow gently for 5 seconds, then relax. Do 10 reps.

Many people find this squeeze settles a sore SI joint almost right away, because the inner thigh muscles help draw the pelvis together.

7. Clamshells

Lie on your side with knees bent and stacked, hips slightly forward. Keep your feet together and lift your top knee a few inches without rolling your pelvis back. Lower slowly. Do 10 to 12 per side.

8. Bird Dog

Start on hands and knees. Slide one leg straight back along the floor, then lift it to hip height while keeping your pelvis level. Add the opposite arm when that feels easy. Hold 3 seconds, return and switch.

This trains the back, glutes and core to work together without loading the spine. For a full beginner plan, see my hip strengthening exercises.

Core and Pelvic Floor Support

The deep core muscles wrap around your middle like a corset, and the pelvic floor forms the base. Together they help hold the pelvis steady, so they play a quiet but real role in SI joint pain.

You don’t need fancy moves here. A gentle exhale with a light draw-in, done during the bridges and bird dogs above, is a good start.

My guide to core strengthening for lower back pain builds on it, and core and pelvic floor training for women covers the pelvic floor side in more depth.

Standing SI Joint Exercises

Standing moves help you carry your strength into daily life. Keep a counter or chair back close for balance.

1. Standing side leg lift. Stand tall, hold the counter, and lift one leg out to the side a few inches with toes pointing forward. Do 10 per side.
2. Standing hip extension. Hold the counter and move one straight leg back a few inches, squeezing the glute without arching your back. Do 10 per side.
3. Supported balance. Stand on one leg with a fingertip on the counter for 20 to 30 seconds, keeping your hips level. Do 2 per side.
4. Mini squat. With feet hip width apart, sit your hips back a few inches as if toward a chair and stand up. Do 10.

SI Joint Exercises for Seniors

If balance, getting on the floor or joint stiffness is a concern, you can do almost this whole routine from a bed, a sturdy chair or standing at the counter. Glute squeezes and pillow squeezes work well while seated. Sit to stand from a firm chair builds the same muscles as a squat.

Go slower, use fewer reps, and rest as long as you need between sets. Consistency matters far more than intensity at any age.

Which SI Joint Exercise Fits Your Day

Moves to Pause While Your SI Joint Is Sore

Some moves often flare a sore SI joint, so take them out for now and add them back slowly once you feel better. These include deep lunges, wide-stance squats, single leg hopping, deep twists, and heavy lifting from the floor.

Long stretches that pull one leg hard across your body, like an aggressive pigeon pose, can also irritate the joint. If a stretch feels good in the muscle but sharp in the joint, skip it. For more gentle options for the lower back itself, see my stretches for lower back pain.

When to See a Doctor or Physical Therapist

SI joint pain is usually a muscle and movement problem, not an emergency. But some symptoms point to something exercise cannot fix. Stop and see a doctor or physical therapist if you notice:

• Numbness, tingling or weakness in your leg or foot
• Pain that started after a fall, an accident or a hard landing
• Pain that wakes you at night, no matter how you lie
• Fever with back or joint pain, or a hot, swollen joint
• Loss of bladder or bowel control, which needs emergency care
• Pain that is no better after 2 to 3 weeks of gentle exercise

A physical therapist can check whether the pain comes from your SI joint, your low back or your hip, and tailor a plan to what they find.

Your This-Week Plan

1. Days 1 to 2: Do pelvic tilts, single knee to chest and the pillow squeeze each morning.
2. Days 3 to 4: Add glute bridges and clamshells, 2 sets of 8 to 10.
3. Days 5 to 6: Add bird dog and two standing moves at the counter.
4. Day 7: Rest or take an easy walk, and note which moves felt best.
5. Every day: Get up from sitting at least once an hour and try not to stand on one hip.

The Bottom Line

SI joint pain exercises work best when they are gentle, even on both sides and done most days. Start with pelvic tilts, knee to chest and the pillow squeeze, then build strength with bridges, clamshells and bird dogs.

Give it a few weeks, pause the moves that flare it, and keep getting up from your chair. If you have numbness, leg weakness, fever or pain after a fall, skip the exercises and get checked first.
