What is the minimum amount of continuous cardiorespiratory exercise recommended before increasing intensity?

The recommended minimum amount of continuous cardiorespiratory exercise before increasing intensity is typically 20 minutes. This duration allows the body to adequately adjust to the current level of exertion, ensuring that cardiovascular and muscular systems are properly warmed up and engaged.

During this 20-minute period, the heart rate elevates, blood flow to the muscles increases, and metabolic processes begin to adapt to the demands of the exercise. By establishing this foundational amount of exercise time, individuals can better gauge their endurance levels and avoid injury by ensuring their body is sufficiently prepared for increased intensity.

This principle is particularly important in exercise programming, as it promotes a safe progression in intensity, helping participants to build their stamina effectively while minimizing the risk of overexertion.
