90-90 Hip Transitions
Hip internal and external rotation
Minimum Effective Dose
50s
The shortest time that still creates real, measurable change. Hit the dose and the benefit starts. Everything after is bonus.
Why it works
Hip rotation is the most commonly lost range in adults who sit. The 90-90 position isolates internal and external rotation without compensating through the spine. Transitioning between sides trains the rotational control that protects knees and lower back.
How to do it
Rotation, not stretch.
Feel the femur roll. If it turns pinchy, reduce range. Discomfort is useful information. Pain is not.
- Sit with both knees bent at 90°, one leg in front, one behind
- Transition both legs to the other side in a windshield-wiper motion
- Focus on the rotation happening at the hip joint, not the knee
- Use hands on the floor for support if balance is an issue
