Final answer:
Warming up for around 10 to 15 minutes before exercise is advantageous as it increases blood flow to muscles, raises body temperature, and reduces the risk of muscle injuries and tendon strains.
Step-by-step explanation:
Warming up before exercising offers several advantages that contribute to a safer and more effective workout. The benefits include the prevention of muscle injuries and tendon strains by preparing the muscles through increased blood flow and heart rate. This gradual adjustment to the higher intensity of the main activity makes warmed-up muscles less likely to be injured. An appropriate warm-up duration is generally around 10 to 15 minutes, which allows enough time for the body temperature to rise and muscles to become more elastic, reducing the risk of injury. Activities such as slow jogging, stretching exercises, or dynamic movements are effective at increasing blood flow and preparing the body for more strenuous exercise.
