Thoracic extension — foam roller
Thoracic mobility — addresses the root of forward head and rounded shoulder pattern
Roller starts just below the shoulder blades. Lift hips to reposition roller one segment lower, hips back down to floor, let upper back drape over roller passively. Breathe out fully at each segment — each exhale gets you slightly deeper. Hold 30–90 sec per segment. Work through 3–4 segments. Correct: extension feels like it originates in the mid-back. Wrong: neck cranking back independently while thoracic barely moves.
