🚀 AI-Enhanced Form Analysis & Comprehensive App Improvements

[ayushjaiswal21]

🔥 Issue Summary

This pull request introduces a comprehensive AI-enhanced form analysis system and provides a detailed roadmap for future improvements to transform KinetiX into a state-of-the-art fitness application.

🎯 Problem Statement

The current KinetiX app has several limitations:

• Basic pose detection with limited exercise coverage (only 13 exercises)
• Simple angle-based analysis without learning adaptation
• No personalized form correction
• Memory leaks in Camera/ML Kit components
• Inefficient database queries causing slow loading

✨ Proposed Solution

I've implemented a comprehensive AI enhancement system that includes:

1. Advanced AI Form Analyzer

• Biomechanical analysis with joint angle calculations
• Muscle activation estimation for different exercise types
• Balance and stability assessment
• Injury risk factor identification
• Personalized feedback based on user history
• Adaptive recommendations for skill progression

2. Enhanced Data Models

• Comprehensive data structures for AI feedback
• Support for form scoring and classification
• User history management for personalization
• Progress tracking and improvement areas

3. Detailed Enhancement Roadmap

• 250-line comprehensive improvement document
• Critical bug fixes identified and solutions provided
• Performance optimization strategies
• 4-phase implementation plan with clear priorities
