What is another purpose of the warm-up phase?

• A. Stretch Muscles
• B. Recovery
• C. Increase Heart Rate & Blood Circulation
• D. Cool-Down

Answer: (C)

The warm-up is designed to gradually bring your body up to activity by increasing heart rate and blood circulation. When your heart rate rises, more blood—and thus oxygen and nutrients—flow to your muscles, helping them perform better and reducing the chance of injury. Warming the muscles and joints also prepares your nervous system for the upcoming work, improving coordination and reaction time.

Stretching might be included, but it’s not the main purpose of warming up; the key goal is to boost blood flow and cardiovascular readiness. Recovery and a cool-down occur after exercise, not during the warm-up.
