How to Add a New Exercise Type

1. Keypoint Index Reference

   • The system uses COCO 17 keypoint format:

                    ○ 0
                   /|\
            1 ●     |     ● 2
           3 ●      |      ● 4
                    |
          5 ●———————————● 6
            |       |       |

        6   │ R.Shoulder   15  │ L.Ankle
        7   │ L.Elbow      16  │ R.Ankle
        8   │ R.Elbow
     

2. Configuration Parameters

   • down_angle: Angle threshold when lowering (degrees)
   • up_angle: Angle threshold when raising (degrees)
   • keypoints.left: Left side three keypoint indices [pt1, pt2, pt3] for angle calculation
   • keypoints.right: Right side three keypoint indices [pt1, pt2, pt3] for angle calculation
   • is_leg_exercise: Whether it's a leg exercise (true/false), affects counting logic
   • angle_point: Keypoint indices [pt1, pt2, pt3] for displaying angle lines on video

3. Example: Adding a New Exercise

   "my_custom_exercise": {
     "name_zh": "我的自定义运动",
     "name_en": "My Custom Exercise",
     "down_angle": 120,
     "up_angle": 170,
     "keypoints": {
       "left": [5, 7, 9],
       "right": [6, 8, 10]
     },
     "is_leg_exercise": false,
     "angle_point": [6, 8, 10]
   }
   

4. Restart the Application

📋 Requirements

• Python 3.9
• Webcam
• Windows/Mac/Linux: Works on CPU by default. Optional GPU acceleration available for source deployments.

🚀 Environment Setup

Installation

1. Clone and install

   git clone https://github.com/yo-WASSUP/Good-GYM.git
   cd Good-GYM
   
   # Create virtual environment
   python -m venv venv
   # Activate (Windows)
   .\venv\Scripts\activate
   # or (Mac/Linux)
   source venv/bin/activate
   
   # Install dependencies
   pip install -r requirements.txt
   

2. Run the application

   python run.py
   

GPU Acceleration (Optional)

If you have an NVIDIA GPU, you can enable GPU-accelerated inference for better performance.

Prerequisites: NVIDIA GPU + NVIDIA Driver installed

Resource Usage:

• CUDA runtime libraries require ~3 GB disk space
• Models use only ~200 MB VRAM — any NVIDIA GPU with 2GB+ VRAM will work

# 1. Replace onnxruntime with the GPU version
pip uninstall onnxruntime
pip install onnxruntime-gpu

# 2. Install CUDA runtime libraries via pip (no need to install CUDA Toolkit manually)
pip install nvidia-cudnn-cu12 nvidia-cublas-cu12 nvidia-cuda-runtime-cu12 nvidia-cufft-cu12 nvidia-curand-cu12 nvidia-cusolver-cu12 nvidia-cusparse-cu12 nvidia-cuda-nvrtc-cu12

The application will auto-detect GPU availability at startup. You can toggle GPU on/off via the "GPU Acceleration" switch in the control panel.

Note: The pre-packaged EXE only supports CPU mode. GPU acceleration is only available when running from source.
