Aplikasi Pemilihan Program Bulking Atau Cutting Pada Tubuh Menggunakan Metode Extreme Programming

This research discusses the development of an application-based Bulking and Cutting program selection system using the Extreme Programming (XP) methodology. The system is designed to assist users in determining appropriate Workout and nutrition programs based on personal data such as body weight, height, and daily activity level. The calculation of daily calorie needs uses the Mifflin-St Jeor formula, while the ideal body weight is calculated using the Broca formula. The results of these calculations are used to determine the user’s program category Bulking, Cutting, or maintenance with calorie adjustments according to each goal. The application was developed using Flutter for the user platform and Laravel as a web-based admin system that manages exercise movement data and nutritional information. Based on the testing results, the system can provide Workout and nutrition recommendations that match the user’s body condition and help users understand their daily calorie needs more easily and interactively.
