Exercises that improve cardiovascular fitness improve body composition, because they a. increase body fat b. increase body tissue c. release energy d. store energy

C) Realease energy  :)

Your answer is C release energy because when you work out or run it takes a lot of your energy because your tired after you do that exercise and you would want to rest or sleep (because it increases sleep) its also because its not A because exercises do not increase body fat you will have to be lazy and eat allot of junk food to increase in body fat its not B because increasing tissues is kind of like body fat which means your gaining more weight and when it came down to rather C, and D I choose C because when your storing energy you are resting like you are sleeping and sleeping is not an exercise for your heart.                                                                                                                                                            Your answer is C.
