An AI fitness trainer is a computer application that utilizes the capabilities of Python, OpenCV, and Media Pipe to guide users through physical fitness routines. The application uses computer vision techniques provided by OpenCV to track the user's movements and provide feedback on form and technique. Media Pipe is used to process the video data and provide Realtime analysis. The application also utilizes machine learning algorithms to provide personalized fitness recommendations and progress tracking. The combination of these technologies provides a highly interactive and effective way for users to improve their physical fitness.
