TITLE Smart Fitness Coaching Platform for Real-Time Exercise Analysis
ABSTRACT This study presents a real-time method for recognizing exercises using a Bidirectional Long Short-Term Memory (BiLSTM) model, specifically designed to work effectively in real-life conditions. Many existing exercise recognition systems depend heavily on synthetic datasets and only use raw joint coordinates. However, these coordinates can vary significantly depending on factors such as different users, camera positions, and environmental conditions. In addition, such systems often do not fully capture the temporal aspect of motion, which leads to reduced performance when used outside controlled environments. To address these issues, the proposed method combines joint angle features with raw spatial coordinates (x, y, z). This hybrid approach allows the model to better handle variations in viewpoint, body proportions, and positioning, while still maintaining precise spatial details of movement. The BiLSTM model is trained using sequences of 30 frames, enabling it to learn how movements change over time. To improve robustness, a diverse dataset was created by combining synthetic data from the InfiniteRep dataset with real-world videos from the Kaggle Workout/Exercises dataset and other online sources. The dataset includes four common exercises: squats, push-ups, shoulder presses, and bicep curls. During testing, the model achieved an accuracy of over 99% and showed strong performance when evaluated on separate real-world datasets, indicating good generalization ability. Comparisons with existing methods demonstrate clear improvements. In addition to exercise classification, the system also includes features such as automatic repetition counting, real-time posture correction, personalized workout and diet planning, and a chatbot that supports both physical and mental well-being. All these features are integrated into a single web-based application, providing a complete and user-friendly fitness solution.
