In the FITT principles, what does "Intensity" refer to?

In the FITT principles, "Intensity" specifically refers to the speed or pace of an exercise. This concept is crucial because intensity determines how hard the body is working during physical activity. It can be measured in several ways, such as heart rate, the amount of weight lifted in strength exercises, or perceived effort levels. Understanding intensity allows individuals to tailor their workouts to meet specific fitness goals, whether it’s improving cardiovascular endurance, building strength, or enhancing overall fitness levels. By adjusting the intensity of workouts, individuals can achieve better results and maintain motivation over time, ensuring that their training remains effective and aligned with their goals.
