The initial text 'Dělej' and the woman starting her exercise routine.

The video features an older woman performing a Tai Chi-like exercise routine on a yoga mat. She is flanked by two animated, simplified drawings of herself performing similar movements. The background is a crumpled grey paper texture. Text overlays appear throughout, offering encouragement and instructions. The video transitions to a screen showing a 28-day challenge interface with daily workout icons, some locked and some unlocked, and a progress tracker. Hands are shown interacting with the interface, tapping on days and highlighting text.
