Rachel wants to improve her body composition by reducing her BMI. She swims with her friends after school two days a week and eats a well-balanced diet. What else should she do to ensure that she properly applies all the necessary FITT principles in her plan?

To apply the FITT principles more fully, Rachel should adjust the frequency and types of exercise in her routine. Adding cardiovascular training and weight training can support fitness and body-composition goals, while eating several low-calorie meals can help manage energy intake. The other choices recommend high-calorie diets or an unnecessarily restrictive diet, which do not fit her goal of reducing BMI.
