Each strength exercise set has its own play/pause timer. This measures the actual time you spend executing the set (not rest time). The total work time is summed across all sets and displayed separately from the overall workout duration.
Cardio exercises use a different interface:
- Large timer display with seconds incrementing
- Play/pause button to track time
- Manual entry option for minutes
- No sets/reps - just duration tracking
When adding an exercise:
- First priority: Last weight used for that exercise in your most recent workout
- Second priority: Template default weight (based on 90kg male standards)
- Fallback: 0 lbs (for custom exercises or bodyweight)
Exercises like pull-ups, push-ups, and dips display cleanly:
- Shows just "12 reps" instead of "0 lbs × 12 reps"
- Weight field available if you add weight (e.g., weighted pull-ups)
- Automatically detects bodyweight vs. weighted exercises
- Open any completed workout from history
- Tap "Repeat This Workout"
- New workout is created with all exercises and sets
- Work times are reset (fresh start)
- Complete the workout
- See side-by-side comparison with the original
Uses SwiftData for local persistence:
- All data saves automatically as you work
- Workouts, exercises, and sets persist between app launches
- Cascade delete relationships (deleting a workout deletes its exercises and sets)
- Schema migration handling for future updates
- Apple Health integration for syncing workout data
- Workout templates and programs
- Progress photos
- Social sharing
- Cloud sync across devices
- Advanced analytics and insights
