# Development Plan: Exercise Diary

## Overview
A desktop GUI application for Linux (CachyOS) to track workout sessions, exercises, and body metrics (weight, etc.).

## Technology Stack
*   **Language:** Python 3
*   **GUI:** `customtkinter` (Modern, clean, supports dark mode - similar to your Video Converter project).
*   **Database:** `SQLite` (Lightweight, local file storage, no server setup required).
*   **Plotting:** `matplotlib` (For visualizing progress/weight trends).

## Core Features (MVP)
1.  **Daily Health Log:**
    *   **Sleep:** Duration (hours) and Quality (1-10 scale).
    *   **Body:** Weight and Waist Circumference.
    *   **Wellness:** Mood/Energy levels.
2.  **Calisthenics Tracker:**
    *   Focus on bodyweight exercises (e.g., Pushups, Squats, Planks).
    *   Track Reps, Time (for statics like Planks), and Difficulty/Variation (e.g., "Knee Pushups" vs "Standard").
    *   RPE (Rate of Perceived Exertion) to track effort as strength increases.
3.  **Motivation & Gamification:**
    *   **Streaks:** Visual indicator of consistency.
    *   **Progress Graphs:** Weight vs. Waist, Sleep Quality vs. Mood.
    *   **"Level 0 to Hero":** Simple milestones to acknowledge starting from a sedentary lifestyle.
4.  **Exercise Library:**
    *   Pre-loaded with basic calisthenics moves.
    *   Ability to add custom exercises.

## Next Steps
1.  Initialize the project environment (virtualenv).
2.  Install `customtkinter` and `matplotlib`.
3.  Set up the database schema.
4.  Build the basic GUI shell.
