Technical Architecture

Base Exercise Class

All exercises inherit from BaseExercise class located in utils/base_exercise.py:

class BaseExercise:
    - coordinate validation
    - angle calculation
    - angle smoothing (rolling average)
    - rep counting logic
    - stage tracking (up/down/extended/flexed)
    - Redis state persistence (optional)

Common Coordinate Patterns

  1. Upper Body (Arms): shoulder → elbow → wrist
  2. Lower Body (Legs): hip → knee → ankle
  3. Hip Thrust: shoulder → hip → knee
  4. Deadlift: hip → knee → ankle (hip extension)

Angle Thresholds

Each exercise defines:

  • min_angle_threshold: Minimum angle for rep completion
  • max_angle_threshold: Maximum angle for starting position
  • buffer_size: Smoothing window (default: 5 frames)

Implementation Summary

✅ Completed

  • 54 exercises implemented across 6 muscle groups
  • All exercises follow the BaseExercise pattern
  • Proper coordinate validation and angle tracking
  • Real-time feedback system
  • Rep counting with stage tracking
  • Smooth angle averaging for accuracy

🔄 Next Steps (Recommendations)

  1. Video Integration: Add demonstration videos for 8 exercises marked as "No video"
  2. API Integration: Register new exercises in main.py endpoints
  3. Testing: Create unit tests for new exercise classes
  4. Documentation: Add usage examples and integration guides
  5. Redis Integration: Ensure all exercises can save/load state from Redis
  6. Form Analysis: Add detailed form feedback for each exercise
  7. Mobile App Integration: Update mobile app to support new exercises

Usage Example

from exercises.chest.incline_dumbbell_press import InclineDumbbellPressCoordinates

# Initialize exercise tracker
exercise = InclineDumbbellPressCoordinates(user_id="user123")

# Process frame coordinates
coordinates = {
    'right_shoulder': [x1, y1],
    'right_elbow': [x2, y2],
    'right_wrist': [x3, y3]
}

counter, feedback, angle, stage = exercise.process_coordinates(coordinates)

print(f"Reps: {counter}")
print(f"Feedback: {feedback}")
print(f"Angle: {angle}°")
print(f"Stage: {stage}")

Notes

  • All exercises use the same BaseExercise inheritance pattern
  • Coordinate validation ensures proper body positioning
  • Angle smoothing prevents false rep counts from jittery tracking
  • Each exercise has customized thresholds for optimal tracking
  • Redis integration ready for persistent state across sessions
