According to the FIIT principle, how often should a beginner engage in cardio training?

For beginners, engaging in cardio training 1-3 times per week is a suitable recommendation, aligning with the FIIT principle, which stands for Frequency, Intensity, Time, and Type. When starting a cardio program, it is important for individuals to allow their bodies to adapt gradually to the new physical demands. This frequency helps prevent injury and ensures that beginners can build cardiovascular endurance without overwhelming themselves.

In the case of beginners, the focus should be on establishing a consistent routine rather than high frequency. Adequate rest days are essential for recovery and development, facilitating improvements in endurance and fitness levels over time. This cautious approach allows individuals to develop the necessary physical adaptations and builds confidence in their exercise routine.

As fitness levels increase, individuals can adjust their training frequency accordingly, possibly moving up to the higher end of the frequency range, making the principle adaptable to varying levels of fitness and experience.
