🏃‍♂️ Exercise Prescription Calculator

A simple and interactive web application built with Python and Streamlit to calculate optimal heart rate zones for physical training.

This tool uses the Karvonen method (Heart Rate Reserve - HRR) and $VO_2max$ to prescribe safe and effective exercise intensity based on the user's age, gender, resting heart rate, and overall fitness level.

Features

• Max Heart Rate Calculation: Uses gender-specific regression formulas or accepts actual data from a stress test.
• $VO_2max$ Integration: Automatically calculates the optimal training percentage based on the formula: %HRR = 60 + (VO2max / 3.5).
• Current vs. Optimal Load: Compares the user's current training heart rate with their optimal target and provides instant feedback.
• Safety Corrections: Adjusts the final target heart rate zone based on the population category (Weakened/Obese, General, or Fit/Active).
• Data Export: Allows users to download the calculated FITT prescription as a .txt report or a .csv data table.

Tech Stack

• Python
• Streamlit (for the web GUI)
• Pandas (for CSV data handling)
