Notes

#Explain why improving cardiorespiratory fitness and muscular strength and endurance are considered good strategies for improving body composition.:Exercise uses energy, and when energy expenditure exceeds energy intake, the difference is made up by burning fat. Thus, improving one's cardio respiratory fitness and muscular strength and endurance can help improve one's body composition by changing the ratio of body tissue to fat.
#Which of the following is a direct benefit of good flexibility?: increased range of motion
#Compare and contrast the curl-up and arm hang test and explain why different tests cannot be used interchangeably: The curl-up tests the strength and endurance of the abdominal muscles, while the arm hang tests the strength and endurance of the arm muscles. Since different muscle groups are developed and tested in different ways, tests for different groups cannot be used interchangeably because the results do not pertain to the same group of muscles.
