Abstract: AI and wearable sensors are revolutionizing the modern workout routine, offering real-time health tracking, tailored exercise plans, and intelligent performance optimization. The present research provides an extensive survey of AI-driven smart fitness systems with focus on upcoming machine learning and deep learning techniques that could be incorporated with wearable gadgets for instant wellness measurement and guidance. It explores cutting-edge techniques such as Convolutional Neural Network, Recurrent Neural Network, Spatio-temporal Graph Convolutional Network, Transformer-based model, and Virtual Fitness Assistants powered by Large Language Model, and delves into the applications of these models for posture correction, activity recognition, adaptive training, physiological recovery analysis, injury-risk prediction, and personalized wellness management. The paper also explores major technical hurdles like multimodal sensor data fusion, computational efficiency on the edge, privacy-preserving federated learning, explainable AI, and long-term personalization. Finally, new research trends such as digital twins, generative AI, and intelligent coaching with context are discussed to pave the way to the future of AI-powered fitness ecosystems. This research offers a technical foundation and insights to computer science researchers, practitioners and students on next generation intelligent fitness systems.
