Exercise Library/ holds per-exercise reference docs (setup, cues, mistakes, progressions) with SVG visuals and a Python-rendered motion pipeline; Workouts/ExerciseFigure renders the bundled *.motion.json rigs as animated stick figures on the exercise screen. Exercises gain a warm-up/main-circuit category, timed exercises display hold time via planSummary, and a completed exercise reopens to a check screen instead of its timers.
