Desk hips fail in a specific order: rotation goes first — the quiet ability to turn thighs in and out that squats, stairs and dance all borrow. The 90/90 position is the rotation gym: one floor shape that finds, measures and fixes what the chair took. Ten minutes, most days, hips reopened.

The Rotation Story

Hips are ball-and-socket joints capable of turning — but chairs only ever ask for one angle, and unused rotation gets repossessed. Restricted hip rotation quietly redirects force to knees and lower back (both terrible at rotation, both known complainers).

The 90/90 Position

Sit with front leg bent 90 degrees (shin across), back leg bent 90 behind — both knees down-ish, spine tall. This shape IS the assessment: the tilting, the back-hip floating, the general indignation all map your current rotation honestly.

The Working Sequence

In the position: lean over the front shin with a flat back (30 breaths), then the switch drill — swiveling both knees side to side through the middle, slow, hands as needed (the swivel is the rotation gym’s cardio). Five minutes total, daily-ish, improvement measurable in weeks.

The Sit-Differently Maintenance

The maintenance program is positional variety: floor-sitting cameos during TV (90/90 included), cross-legged chair spells, the occasional squat while browsing your own phone. Hips keep whatever ranges get visited — the chair was never the enemy; the monopoly was.

Assess in the shape, breathe over the shin, swivel through the middle, vary the sitting. Rotation left quietly and returns the same way — five floor minutes at a time, starting during tonight’s episode.
