90–90 Hip Transitions

Hip internal and external rotation

Minimum Effective Dose

1 min

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 on the floor with both knees bent at 90 degrees, one in front and one to the side. Sit tall and try to keep your torso upright
Swing both knees to the opposite side, transitioning through the middle
Move slowly and feel the femur roll in the hip socket. Reduce range if it pinches
Use hands on the floor for support if balance is an issue

Variants
