Change

Replace the blocky silhouette with detailed front/back muscle anatomy from the MIT-licensed MuscleMap artwork used by openGym. Analytics keeps weekly volume shading, muscle selection, and recovery/volume drill-downs. Bundle artwork attribution and register it with Flutter’s license registry.

Existing users without a saved gender choice must complete a one-time setup before entering the app. Save Male, Female, or Prefer not to say in persistent settings; the saved gender selects diagrams throughout the app. Gender changes are available only in Profile after setup. Remove independent diagram selectors. New users provide the choice during onboarding. Failed saves leave setup open for retry and preserve the previous saved choice.

Show labelled Stretched (blue) and Contracted (rose-red) views for supported exercises, with movement cues and intensity legends. Shades illustrate catalogue muscle involvement and standard technique, not measured stretch, force, or live movement. Custom, isometric, and unsupported exercises show involvement without inferred phases. Analytics retains its volume scale.

Validation

  • 87 relevant Flutter tests passed, including upgrade prompting, persistence across restart, failed saves, shared diagrams, onboarding, Profile, exercise phases, Analytics, and changelog parsing.
  • Targeted static analysis and whitespace checks.
  • Corrected shoulder-press targets and controlled gender picker behavior from review; both review threads resolved.

Release notes

Added the feature to root CHANGELOG.md under 2.1.7. The repository is already at 2.1.6+64; this feature does not downgrade or publish a release.

Summary by CodeRabbit

  • New Features
    • Added interactive front and back muscle maps with weekly volume shading, muscle selection, and drill-down details.
    • Exercise details now show illustrative stretched and contracted muscle phases, with distinct intensity colors for supported exercises.
    • Added an optional gender selection during onboarding and in Profile; the choice selects muscle diagrams throughout the app.
  • Notes
    • Phase maps illustrate standard technique and catalogue muscle involvement, not live stretch or force. Custom and unsupported exercises show target involvement without phase views.

Walkthrough

The app adds persistent gender and body-diagram preferences, interactive front and back muscle maps, and illustrative stretched and contracted exercise views for supported exercises.

Changes

Muscle diagrams and exercise phases

Layer / File(s) Summary
Profile and diagram preferences
workout-logger/lib/data/body_figure.dart, workout-logger/lib/services/settings_provider.dart, workout-logger/lib/screens/widgets/gender_picker.dart, workout-logger/lib/screens/onboarding_screen.dart, workout-logger/lib/screens/widgets/profile_sections.dart, workout-logger/test/muscle_preferences_and_phases_test.dart, CHANGELOG.md
The settings provider stores gender and an optional body figure. Onboarding and profile controls save these values, and tests cover defaults, persistence, invalid values, and onboarding.
Interactive body diagrams
workout-logger/lib/data/body_geometry.dart, workout-logger/lib/screens/widgets/body_heatmap.dart, workout-logger/lib/screens/widgets/analytics_overview.dart, workout-logger/lib/screens/widgets/muscle_detail_sheet.dart, workout-logger/test/body_heatmap_test.dart, workout-logger/test/muscle_preferences_and_phases_test.dart, workout-logger/pubspec.yaml, workout-logger/lib/main.dart, workout-logger/THIRD_PARTY_NOTICES.md
Front and back diagrams use male or female geometry and support volume shading, selection, and figure controls. Analytics and muscle details display the maps. Tests cover rendering and selection; startup registers the geometry license notice.
Exercise phase diagrams
workout-logger/lib/data/exercise_muscle_motion.dart, workout-logger/lib/screens/widgets/exercise_muscle_map.dart, workout-logger/lib/screens/widgets/exercise_details_sheet.dart, workout-logger/test/muscle_preferences_and_phases_test.dart
The exercise motion catalogue supplies phase descriptions for mapped exercises. Exercise details show phase controls and activation values when motion data exists, and target involvement otherwise. Tests cover phase views and unsupported exercises.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 815ad

The change is mergeable with awareness that the shoulder-press test does not yet protect against a missing required muscle target.

Review comments at @workout-logger/lib/data/exercise_muscle_motion.dart:
- Around line 52-56: Update the target muscle IDs in _shoulderPress to use the
catalogue’s canonical shoulders ID alongside triceps, so ExerciseMuscleMap can
match shoulder activations in both phase views.

Review comments at @workout-logger/lib/screens/widgets/gender_picker.dart:
- Around line 10-26: Update GenderPicker so its displayed selection stays
controlled by settings.userGender, or otherwise resets when its onChanged save
fails; do not rely on initialValue or ValueKey(value) to revert the field.
Coordinate with PreferencesSection and setUserGender so a failed persistence
attempt restores the previously saved gender while successful external changes
still update the picker.
