90/90 Hip Stretch: Improve Hip Rotation the Simple Way
How to do the 90/90 hip stretch for internal and external hip rotation, transitions, easier setups for tight hips, and why it helps squats and sitting.
By Ayoub Farid · · 2 min read
The 90/90 hip stretch trains something most stretches ignore: hip rotation. Both knees are bent at 90°, one leg rotated out in front of you, the other rotated in behind you. It stretches the front hip into external rotation and the back hip into internal rotation at the same time.
Why hip rotation matters
Healthy hips rotate in both directions. Sitting all day limits that, and stiff rotation shows up in squats, running, getting out of a car and even sitting cross-legged. Better rotation often makes hips feel freer overall. More in hip mobility exercises.
How to do the 90/90
- Sit on the floor.
- Place your right leg in front of you, bent at 90°, shin parallel to your hips.
- Place your left leg out to the side and behind you, also bent at 90°.
- Sit tall. Use your hands on the floor behind you if needed.
- Front hip stretch: hinge forward over your front shin with a straight back. 30 seconds.
- Back hip stretch: turn your torso toward the back leg. 30 seconds.
- Switch sides.
90/90 transitions (switches)
With hands behind you, lift both knees and rotate them to the other side, landing in the mirrored 90/90. Move slowly, 5–10 switches. It's a great active mobility drill and warm-up.
Easier set-ups
- Sit on a cushion to raise your hips.
- Open the angles wider than 90° at first.
- Hands behind you for support.
- Keep the back knee off the floor if internal rotation is very limited.
Common mistakes
- Collapsing to one side. Sit tall and balanced.
- Forcing the knees down. Let range come gradually.
- Knee pain. Reduce the angle or support the knee with a pillow.
When to use it
- Warm-up before squats or running.
- Daily hip routine for desk workers.
- Rest days for lifters; see stretches for weightlifters.
Do it with Suppl
The 90/90 hip stretch is in Suppl's hips and glutes library (10 stretches). Combine it with pigeon pose and the frog stretch for a complete hip session, or follow stretches for tight hips.
Progressing the 90/90
Week 1–2: hands behind you, upright torso, short holds. Week 3–4: lean forward over the front shin for 30–45 seconds and add switches. After that, try switches with your hands lifted off the floor, which requires real hip control. Many people notice that squats and sitting cross-legged feel easier once 90/90 switches become smooth.
Frequently asked questions
Why is the 90/90 so hard?
Most people have limited internal rotation from sitting. It improves with regular practice.
How long should I hold the 90/90?
30–60 seconds per position, or do 5–10 slow switches.
Is the 90/90 good for hip pain?
It can help stiffness. Pinching or sharp pain means stop and get advice.
Should I feel it in both hips?
Often yes: front hip in the glute, back hip in the front or side.
