If you’ve ever dealt with sacroiliac (SI) joint pain, you know how frustrating it can be. One wrong move—sitting too long, standing up too fast, even just rolling over in bed—and bam, that deep, nagging ache is back. It’s the kind of discomfort that makes you extra cautious about, well… everything.
The good news? The right exercises can help. Not the “push through the pain” kind, but gentle, targeted movements that loosen up tight muscles, strengthen weak spots, and bring balance back to your hips and lower back. Let’s dive into a few simple but effective moves that can help you find relief.
1. Pelvic Tilt – Your New Best Friend

Think of this as a small but mighty movement. Pelvic tilts help wake up your core and stabilize your SI joint without putting too much stress on it.
- How to do it: Lie on your back with your knees bent and feet flat on the floor. Gently rock your pelvis backward, pressing your lower back into the floor. Hold for a couple of seconds, then release.
- Why it Works: It strengthens deep core muscles that support your SI joint. Plus, it’s a great way to reconnect with your body’s movement patterns.
2. Knee-to-Chest Stretch – Loosen Up Those Hips

Tight hip muscles can pull on your SI joint, making things worse. This stretch helps ease tension and increase mobility.
- How to do it: Lie on your back, bring one knee toward your chest, and hold it there for about 20-30 seconds. Switch sides.
- Pro Tip: Keep your opposite leg relaxed to avoid unnecessary strain.
3. Seated Figure-4 Stretch – Ahh, That’s the Spot
Ever feel like your lower back and hips are locked up? This stretch helps open everything up in the best way.
- How to do it: Sit in a chair, cross one ankle over your opposite knee, and gently press down on the raised knee until you feel a stretch in your hip. Lean forward slightly for a deeper stretch.
- Bonus: It can also help with sciatica symptoms, which often tag along with SI joint pain.
4. Gentle Core Activation – Because Stability Matters
Your core is the unsung hero of SI joint health. Strengthening it—gently—can take some of the strain off your lower back.
- Try This: Lying on your back, engage your deep core muscles as if you’re zipping up a tight pair of jeans. Hold for a few seconds, then relax.
- Small effort, big impact.
5. Cat-Cow Stretch – Because Movement = Relief

If your lower back feels stiff, this classic yoga move is a game changer.
- How to do it: On hands and knees, arch your back up (like an angry cat), then drop your belly down while lifting your head (hello, happy cow). Move slowly, syncing with your breath.
- Why it Helps: It improves mobility, encourages circulation, and just feels good.
Final Thoughts: Move Gently, But Move
The trick with SI joint pain? Stay active, but don’t overdo it. These exercises can help you regain mobility, reduce stiffness, and keep your pain from flaring up. Listen to your body, stay consistent, and if something doesn’t feel right, back off and modify.
