What is the duration range for proper cardiovascular training?

The duration range for proper cardiovascular training is typically recommended to fall between 20 to 45 minutes. This timeframe is considered optimal for achieving various fitness benefits including improved cardiovascular efficiency, endurance, and calorie burning. Engaging in cardiovascular exercise within this range allows individuals to sustain a moderate to vigorous intensity that promotes heart health without leading to excessive fatigue or an increased risk of injury.

Shorter durations may not provide sufficient time to effectively raise heart rates to beneficial levels, while longer sessions could lead to diminishing returns, especially for those who may not be conditioned for extended exercise. Therefore, training for a duration of 20 to 45 minutes strikes a balance that is both beneficial and accessible for most individuals.
