FitBuddy: A Personalized Digital Fitness Trainer for Health Monitoring and Lifestyle Management

Abstract: The rapid growth of sedentary lifestyles and associated health risks has led to increased interest in mobile health (mHealth) technologies that support fitness and well-being. This paper presents FitBuddy, a personalized digital fitness trainer designed to provide integrated services including workout planning, diet recommendations, body mass index (BMI) calculation, and calorie tracking. The system adopts a user-centered design approach to improve usability and engagement while leveraging personalization techniques to enhance adherence to fitness routines. Prior studies demonstrate that personalized mHealth applications significantly influence user motivation and long-term behavioral change by integrating goal setting, feedback, and adaptive recommendations. The proposed system combines these principles into a unified platform, offering accessibility and efficiency. Experimental observations indicate that integrated tracking and personalization improve consistency and user satisfaction. The study concludes that digital fitness systems such as FitBuddy can effectively bridge the gap between professional fitness guidance and everyday accessibility.
