What is a primary purpose of a warm-up before exercise?

• A. Reduces heat in muscles
• B. Prepares the body for exercise
• C. Increases risk of injury
• D. Causes fatigue

Answer: (B)

The main idea behind a warm-up is to prepare the body for activity by gradually getting everything ready for movement. As you start warming up, your heart rate rises and blood flow to the muscles increases, so oxygen and nutrients arrive where they’re needed. Muscles and joints also heat up, becoming more elastic and easier to move, which helps you perform with better range of motion. The nervous system is nudged into gear as well, so your muscles respond more quickly to signals. All of this means you can start the main exercise with less risk of strains and you’ll likely perform more effectively, with less immediate fatigue. That choice isn’t about reducing heat or energy; warm-ups raise temperature and readiness. It also isn’t about increasing injury risk or causing fatigue; the purpose is to lower injury chances and feel more prepared, not exhausted.
