I agree with Robert Hutchins who said, "Whenever I get the urge to exercise, I lie down until the feeling passes away."

To answer the questions and understand the correct answers, here's an explanation for each question:

1. In this question, Joey is lifting a heavy backpack off the ground and keeping his legs straight. The correct answer is D. leg muscles and keep his back straight. By keeping his legs straight, Joey is not utilizing his leg muscles effectively and risking injury to his back. To lift the backpack safely and efficiently, he should bend his legs and use his leg muscles while keeping his back straight.

2. This question relates to Jason trying to copy his friend's form in a modified hurdler stretch. His friend is more flexible, sits on the ground, keeps a slight knee bend, touches his toes, tucks his head, stretches through the pain, and wears loose clothing. The correct answer is C. incorrect analysis, except for keeping a slight knee bend. While keeping a slight knee bend is beneficial, the other aspects, such as stretching through the pain and tucking the head, are incorrect and can lead to injury. Jason should not copy his friend's form entirely but rather focus on keeping a slight knee bend.

3. The coach asks the class to perform perfect modified push-ups. Among the options given, the correct answer is A. Jason has his toes on the floor, legs and back in a straight line, hands under his chest, and elbows bent to 90 degrees. Jason's form aligns with the proper technique for modified push-ups.

4. Kai is struggling while jogging, and to assess her intensity and maintain safety, she should use the method of trying to hold a short conversation with you. The correct answer is C. trying to hold a short conversation with you. If she can comfortably hold a conversation while jogging, it indicates that she is exercising at a moderate intensity, which is appropriate for safety.

5. Among the options for home-made equipment, the appropriate ones are the welcome mat and your sister's jump rope. The correct answer is C. the welcome mat and your sister's jump rope. Using these items is safe and suitable for exercise. The other options, such as using a brick, rope, stick, old bottles, or neighbor's bicycle inner tubes, may not be safe or appropriate for exercise.

6. Recalling the FITT principles (Frequency, Intensity, Time, and Type), the principle used to continue exercising regularly and maintain the benefits gained is the reversibility principle. The correct answer is C. reversibility. This principle highlights the importance of maintaining regular exercise to retain the benefits achieved.

7. Running up a hill instead of on a flat surface will increase the principle of fitness known as intensity. The correct answer is A. intensity. Running uphill requires more effort and engages different muscle groups, thereby increasing the intensity of the exercise.

8. The scenario demonstrating the training principle of overload is when Joey starts to do more than he normally does in training. The correct answer is B. Joey starts to do more than he normally does in training. The overload principle states that to make progress, the body must be challenged beyond its current capabilities.

9. The scenario demonstrating the training principle of progression is when Joey slowly builds from jumping without a medicine ball to with a medicine ball. The correct answer is B. Joey slowly builds from jumping without a medicine ball to with a medicine ball. The progression principle suggests that gradual increases in intensity or volume of exercise lead to improvement and reduce the risk of injury.

10. The coach plans to change the practice session by lengthening it to provide more opportunity for skill practice. By doing this, the coach is using the fitness principle of time. The correct answer is C. time. Increasing the duration of practice sessions allows for more time to focus on developing skills.

11. Chantelle wants to win a jump rope competition and believes that jumping rope is the best way to get in shape. She is utilizing the principle of fitness known as specificity. The correct answer is C. specificity. This principle states that to improve in a specific activity or sport, you should focus your training on that activity.

12. To develop bigger muscles, Kevin can achieve this by engaging in strength training exercises and following a proper nutrition plan rather than resorting to options such as muscle implant surgery or reading muscle magazines in class. The correct answer is D. read muscle magazines in class. Effective strength training exercises targeting specific muscle groups combined with proper nutrition are necessary for muscle growth.
