Target Heart Rate for Weight Loss Calculator
To effectively lose weight through exercise, it's crucial to work within your target heart rate zone. This zone represents the intensity of your workout that maximizes fat burning while remaining safe and sustainable. The most common method to estimate your maximum heart rate is the Fox formula, which subtracts your age from 220. Your target heart rate for weight loss is typically between 60% and 85% of this maximum heart rate. For example, if your maximum heart rate is 180 beats per minute (bpm), your target weight loss zone would be between 108 bpm (60%) and 153 bpm (85%).
Typically between 60% and 85% for effective fat burning.

// Calculate Maximum Heart Rate using the Fox formula
var maxHeartRate = 220 – age;
// Calculate Target Heart Rate for weight loss
var targetHeartRate = maxHeartRate * (weightLossIntensity / 100);
