The 'I' in FITT stands for Intensity. In the FITT principle, which is a foundational guideline for developing an effective exercise program, intensity refers to how hard a person works during physical activity. This aspect is crucial because it helps individuals achieve specific fitness goals, whether it's increasing strength, improving cardiovascular health, or enhancing endurance.

Understanding intensity involves knowing the appropriate level at which to exercise, which can range from low to moderate to high, depending on the individual's fitness level and objectives. Adjusting the intensity of workouts is vital for ensuring they are challenging enough to promote adaptation and improvement while also being safe and manageable.

The other options do not represent the key component of the FITT framework. Injury risk refers to the potential for harm during physical activity, involvement does not specifically relate to the structured approach of exercise programming, and immediacy does not pertain to the parameters of fitness training indicated by FITT.
