## Overview

Fitness & Diet Tracker is a two-member web app for following personalized nutrition and training plans and recording daily progress. The user selects a member and date, reviews diet or training guidance, checks off adherence or workout sets, and saves or exports logs. Separate views provide a weight-loss forecast and exercise tutorials. The excerpts show the app’s view composition, local-storage persistence, and log-file API implementation; the exact client-to-API wiring is only partially shown, so that relationship is marked unverified.

Main entry points: [`src/App.jsx`](https://github.com/manivask/fitness-tracker/blob/main/src/App.jsx) (App Shell), [`src/components/TrainingView.jsx`](https://github.com/manivask/fitness-tracker/blob/main/src/components/TrainingView.jsx) (Training Split and Set Tracking), [`dailyLogsPlugin.js`](https://github.com/manivask/fitness-tracker/blob/main/dailyLogsPlugin.js) (Daily Log API), [`src/components/WorkoutTutorials.jsx`](https://github.com/manivask/fitness-tracker/blob/main/src/components/WorkoutTutorials.jsx) (Workout Tutorials)
