What percentage of a person's maximum heart rate is typically considered the lower training threshold?

The lower training threshold is typically set at around 60% of a person's maximum heart rate. This benchmark is significant because exercising at or above this percentage is generally deemed effective for cardiovascular fitness. Training within this range ensures that the heart is sufficiently challenged, promoting improvements in endurance, overall fitness levels, and the efficiency of the cardiovascular system.

When aiming to achieve health benefits and enhanced physical performance, it’s essential to reach this lower threshold, as training under this level may not invoke the necessary physiological adaptations. It strikes a balance between being vigorous enough to make a difference without being excessively strenuous, particularly for individuals who may be new to exercise or returning after a hiatus.
