## Caption

Sitting crushes your thoracic spine into a C-shape and switches off three major muscle groups every day. Your hip flexors shorten, your glutes stop firing, your spine rounds forward. Your body adapted to a chair and got stuck in chair-shape. These four drills rebuild the exact muscles sitting damages most. Save this.

Drop BASICS in the comments for my Grade 1 Mobility programme. 15 minutes a day, any level.
