On Day 1, we’ll set up the AI Fitness Coach app using React Native and install core dependencies for pose detection, voice control, and AI-driven health tracking.
1. What Is the AI Fitness Coach?
✅ Tracks Exercises in Real-Time → AI detects body movements using pose estimation.
✅ Personalized Workout Plans → AI adapts exercises based on user goals.
✅ Voice-Controlled Coaching → Users speak commands, AI starts workouts.
✅ AI-Based Form Correction → AI analyzes posture and gives instant feedback.
2. Tech Stack Overview
| Feature | Tool / Library |
|---|---|
| AI Pose Detection | TensorFlow.js (PoseNet or BlazePose) |
| Workout Voice Control | Expo Speech & React Native Voice |
| AI Insights & Tracking | GPT-4 for AI Workout Analysis |
| Real-Time Health Data | Google Fit & Apple HealthKit API |
| UI Framework | React Native (Expo CLI) |
3. Initializing the Project
✅ Step 1: Create a React Native Project with Expo
npx create-expo-app ai-fitness-coach
cd ai-fitness-coach
✅ Step 2: Install Core Dependencies
npm install @tensorflow/tfjs @tensorflow-models/pose-detection expo-camera expo-sensors react-native-reanimated react-native-gesture-handler
expo install expo-av react-native-voice react-native-svg
4. Project Folder Structure
/ai-fitness-coach

└── .env
5. Setting Up Navigation
✅ Step 1: Install React Navigation
npm install @react-navigation/native react-native-screens react-native-safe-area-context react-native-vector-icons react-native-reanimated react-native-stack
✅ Step 2: Modify App.js for Navigation
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import HomeScreen from './src/screens/HomeScreen';
const Stack = createStackNavigator();
export default function App() {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="Home">
<Stack.Screen name="Home" component={HomeScreen} />
</Stack.Navigator>
</NavigationContainer>
);
}
6. Creating the Placeholder Home Screen
✅ Step 1: Create HomeScreen.js
import React from 'react';
import { View, Text, Button, StyleSheet } from 'react-native';
export default function HomeScreen({ navigation }) {
return (
<View style={styles.container}>
<Text style={styles.title}>AI Fitness Coach</Text>
<Button title="Start Workout" onPress={() => alert('Workout feature coming soon!')} />
<Button title="View Health Stats" onPress={() => alert('Health tracking coming soon!')} />
</View>
);
}
const styles = StyleSheet.create({
container: { flex: 1, justifyContent: 'center', alignItems: 'center' },
title: { fontSize: 24, fontWeight: 'bold', marginBottom: 20 },
});
7. Running the Basic App
✅ Run the App
npx expo start
You should see:
- App title: “AI Fitness Coach”
- Two Buttons: “Start Workout” & “View Health Stats”
8. Key Concepts Covered
✅ Set up Expo React Native project
✅ Installed navigation & core dependencies
✅ Created basic Home Screen layout
9. Next Steps: Integrating Pose Detection for Workout Tracking
Tomorrow, we’ll:
- Set up the camera for real-time pose detection.
- Integrate TensorFlow.js PoseNet to track body movements.
