Which of the following is NOT a component of the FITT principle?

The FITT principle is a framework used to guide the development of an effective exercise program, encompassing four key components: Frequency, Intensity, Time, and Type. Each of these components plays a vital role in structuring an exercise routine to achieve specific fitness goals.

Frequency refers to how often a person engages in physical activity or exercise sessions. Intensity indicates the level of effort or exertion put into the exercise, which can relate to heart rate, perceived exertion, or the amount of weight lifted. Time represents the duration that each exercise session lasts.

The term "FMuscle" does not align with any recognized component of the FITT principle. While muscle involvement can relate to the type of exercises performed, it does not stand alone as a distinct factor within the FITT framework. This makes "FMuscle" the correct answer, as it is not one of the established components that contribute to designing a balanced and effective exercise program.
