Answer:
The f.i.t.t. principle stands for frequency, intensity, time, and type of exercise. By altering any of these variables, you can change your workout routine and avoid boredom. For example, changing the frequency of your workouts to more or fewer days per week, increasing the intensity of your exercises, changing the type of exercise or adding new exercises to your routine, and varying the duration or time of your workouts can all help prevent boredom during workouts. This principle allows you to make gradual changes to your workout routine, which can keep you engaged, motivated, and challenged.
