The FITT principle stands for Frequency, Intensity, Time, and Type. Each of these components represents a key aspect to consider when planning an effective exercise program:

• Frequency: How often a workout or exercise session takes place, typically measured in days per week.
• Intensity: How hard or strenuous the workout is, reflecting the level of effort put into the exercise.
• Time: The duration of each workout session, indicating how long the exercise lasts.
• Type: The specific kind of exercise done, such as running, weightlifting, swimming, or stretching, chosen based on fitness goals.

These four components help create a structured, customizable, and effective workout plan tailored to individual fitness levels and goals, supporting improvements in endurance, strength, weight loss, or rehabilitation.
