How to Use This Tracker

1. Run the Script: Save the script as health_tracker.py and run it with Python.
2. Menu Options: You’ll see a menu to add exercises, meals, weights, or view the summary.
3. Data Storage: The tracker saves data in a health_data.json file in the same directory, so it persists between runs.

Extensions and Improvements

• Data Visualization: You can use libraries like matplotlib or seaborn to create graphs of your progress over time.
• User Interface: Consider creating a GUI with libraries like tkinter for a more user-friendly experience.
• Health Metrics: Add more health metrics (like sleep hours, blood pressure) to track.
• Reminders: Implement reminders for activities or meal logging.
