Add New Exercise

Instructions

When adding a new exercise to vibereps:

1. Read the template at exercises/_template.json for the JSON structure

2. Choose a detection type based on the exercise motion:

   • angle - Joint angle changes (squats, pushups)
   • height_baseline - Vertical movement from baseline (calf raises)
   • height_relative - Position relative to reference point (jumping jacks)
   • tilt - Torso lean (side stretches)
   • distance - Body parts approaching each other (standing crunches)
   • width_ratio - Shoulder/hip width ratio (torso twists)
   • quadrant_tracking - Circular arm motion (arm circles)

3. Create the JSON config in exercises/{exercise_name}.json

4. Test detection by running the tracker

MediaPipe Landmark IDs

Key landmarks for detection:

• Shoulders: 11 (left), 12 (right)
• Elbows: 13 (left), 14 (right)
• Wrists: 15 (left), 16 (right)
• Hips: 23 (left), 24 (right)
• Knees: 25 (left), 26 (right)
• Ankles: 27 (left), 28 (right)
