• Workout Tracking: Log workouts (sets, reps, day) linked specifically to a customer.
• Relational Data: Uses JPA/Hibernate to link Workouts to Customers via a Foreign Key (worker_id).
• CRUD Operations: Full support for Creating, Reading, Updating, and Deleting workouts.

• Language: Java
• Framework: Spring Boot (Web, JPA)
• Database: MySQL (configured via application.properties)
• Build Tool: Maven
