What is the target heart rate zone for effective cardiovascular training?

The target heart rate zone for effective cardiovascular training is typically set between 50-85% of maximum heart rate. This range is considered optimal because it allows individuals to exercise at a level that enhances cardiovascular fitness while minimizing the risk of overexertion or injury. Training within this zone ensures that the heart and lungs work efficiently to supply oxygen to the muscles, which is essential for improving endurance and overall cardiovascular health.

Exercising below 50% usually does not provide sufficient stimulus to improve cardiovascular fitness, while exercising above 85% may lead to exhaustion or injury without proportional benefits for most individuals. Therefore, targeting the heart rate between 50-85% helps maintain a balance between challenge and safety during aerobic exercise.
