## Overview

This is a Windows console fitness tracker. The user starts the app, then uses its menus to manage an account and track workouts, cardio, nutrition, and goals; progress and calendar views present recorded data. FitnessApp coordinates the interface and domain managers, while User handles credentials and per-user files. The excerpts show workout and goal updates and some file access, but not the full login, cardio, or nutrition flows, so those connections are omitted or marked unverified.

Main entry points: [`FitnessApp.cpp`](https://github.com/mxminh/fitness_tracker_app/blob/master/FitnessApp.cpp) (App menus), [`User.cpp`](https://github.com/mxminh/fitness_tracker_app/blob/master/User.cpp) (User file access), [`main.cpp`](https://github.com/mxminh/fitness_tracker_app/blob/master/main.cpp) (Program entry), [`Workout.cpp`](https://github.com/mxminh/fitness_tracker_app/blob/master/Workout.cpp) (Workout log)
