What is the target percentage for intensity to improve cardiovascular fitness?

To improve cardiovascular fitness, the target intensity is typically set between 60% to 80% of an individual’s maximum heart rate. This range is effective for enhancing aerobic capacity and overall cardiorespiratory endurance. When exercising at 60% intensity, individuals are engaging in a moderate level of activity that elevates the heart rate and promotes heart and lung efficiency, thereby leading to improvements in cardiovascular health.

Conversely, lower intensities, such as 50%, may not sufficiently challenge the cardiovascular system to elicit noticeable fitness improvements. While exercising at higher intensities like 70% to 80% can also be effective, it may be less sustainable for longer durations and might not be suitable for all fitness levels. The 60% benchmark serves as a safe and effective starting point for many individuals aiming to enhance their cardiovascular fitness, making it a commonly accepted recommendation for those beginning a fitness program.
