What is the minimum duration for the conditioning component of an exercise training session?

The minimum duration for the conditioning component of an exercise training session is 20 minutes. This guideline is grounded in the objective of achieving meaningful cardiovascular and muscular adaptations associated with regular exercise. A duration of at least 20 minutes ensures that participants engage in sufficient activity to elevate their heart rate and maintain it at an appropriate intensity for a period conducive to endurance improvements and caloric expenditure.

Shorter durations, such as 5 or 15 minutes, may not provide enough time for the body to effectively increase oxygen consumption, improve cardiovascular function, or elicit the physiological benefits associated with regular exercise. Engaging in exercise for at least 20 minutes also aligns with recommendations aimed at promoting health and fitness while minimizing the risks of injury and maximizing the overall effectiveness of an exercise program.
