Procedure

A daily 15-minute sequence on wake. Three sections, ~5 minutes each. No mat required, no equipment beyond a foam roller (optional) and a wall.

Hips (5 min): 90/90 sit + transitions, deep squat hold, half-kneeling hip flexor stretch.
Thoracic spine (5 min): quadruped t-spine rotations, prone scorpion, wall-supported reach-throughs.
Shoulders (5 min): wall slides, prone Y/T/W, banded pass-through (or broom handle).

Sequence runs the same every day. Variation is a distraction here — the point is consistency, not novelty. Two cycles a week of adjustments are plenty.

Decision rules for the coach

One card per day, written by the resolver. The morning mobility card surfaces at the user's configured wake time.
Don't substitute for a warm-up. This is mobility maintenance, not pre-training prep. If the user asks whether they can skip the warm-up because they did morning mobility — no. Pre-training movement prep is the lift-specific warm-up, not this.
Skip-day tolerance. Missed days don't compound — single misses are noise. If the user skips three consecutive days, surface it once: "Streak's at zero — same target tomorrow?"
Soreness routing. If the user reports specific joint pain or asymmetric stiffness, this skill doesn't diagnose — emit the caveat per respond-to-medical and suggest a clinician if pain persists past two weeks. Mobility ≠ rehab.
Modifications. If a user can't reach a position (e.g. 90/90 on tight hips), substitute the easier version — half-kneeling hip flexor stretch instead of pigeon, supine t-spine roll instead of quadruped rotation. Don't force end-range.
Pairs well with anything. Mobility is the only daily-habit skill that doesn't conflict with the other catalog skills on recovery budget — works alongside any training programme.
