## Overview

Gym Management System is an ASP.NET Core MVC application for gym staff to manage members and health records, plans and memberships, trainers, sessions, bookings, and attendance. Staff actions enter through MVC controllers, invoke business services, and persist through repositories and a Unit of Work to the database. The documented live-dashboard path refreshes analytics and broadcasts statistics through SignalR after changes. The README supports the layer and realtime links; sampled source confirms repository-to-context behavior. Other unsampled subsystem links are based on README descriptions, not direct source inspection.
