Target Heart Rate Formula:
| From: | To: |
Target Heart Rate (THR) is the desired range of heart rate achieved during exercise that enables the heart and lungs to receive the most benefit from a workout. This calculation approximates your target heart rate based on age and weight.
The calculator uses the formula:
Where:
Explanation: While weight doesn't directly appear in the formula, it influences heart rate through fitness level. The 70% intensity factor represents a moderate exercise level appropriate for most fitness goals.
Details: Training within your target heart rate zone ensures you're exercising at the right intensity to improve cardiovascular fitness, burn fat effectively, and avoid overexertion.
Tips: Enter your age in years and weight in kilograms. All values must be valid (age between 1-120, weight > 0). For best results, measure your resting heart rate in the morning before getting out of bed.
Q1: Why is weight included if it's not in the formula?
A: Weight influences heart rate through fitness level. Heavier individuals typically have higher resting heart rates, which affects their target zone calculation.
Q2: What if I want to exercise at a different intensity?
A: For vigorous exercise (80-85% intensity), multiply by 0.8-0.85 instead of 0.7. For light exercise (50-60% intensity), multiply by 0.5-0.6.
Q3: Are there limitations to this calculation?
A: This formula provides an estimate. Individual variations in fitness, medications, and health conditions can affect actual target heart rate.
Q4: How often should I check my heart rate during exercise?
A: Check periodically throughout your workout, especially when changing intensity. Many fitness trackers provide continuous monitoring.
Q5: Should everyone use the same target heart rate?
A: No. People with certain health conditions, athletes, and older adults may need adjusted targets. Consult a healthcare provider for personalized advice.
