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?
a. she should add more cardiovascular training and weight training to her exercise routine and eat several low-calorie meals throughout the day. b. she should increase her swimming workouts to five days a week and eat a high-calorie diet that equals 2,500 calories. c. she should add a few days of weight training to her exercise routine and consume 4,000 calories a day. d. she should eat a high-protein, low-carbohydrate diet and add five days of weight training to her exercise routine.

FITT stands for Frequency, Intensity, Time and Type. That means that when you exercise you must take in to account how often you will exercise (frequency), how hard you work (intensity), at that time of the day (time) and what type of exercise you do (type). Those factors must be balanced according to your personal goals. To reduce the BMI the best option is A. she should add more cardiovascular training (increase frequency) and weight trianing (type) while eating more several low-calorie meals through out the day (this will contribute to accelerate metabolism even though she decrases the total consumption of calories). May be you get confused with the option D, but this is not the best to reduce the BMI because high-protein low carbohydrate diet trends to cause increase of mass.
