What is the purpose of warm-up exercises?

Warm-up exercises primarily aim to increase heart rate and blood supply to the muscles. This physiological response enhances blood circulation, which helps to deliver more oxygen and nutrients to the muscles that will be used during subsequent physical activity. By gradually elevating the heart rate, warm-up exercises prepare the cardiovascular system for more intensive efforts, reducing the risk of injuries and allowing the body to perform at its best.

While improving flexibility, enhancing strength, and focusing on mental readiness are all beneficial aspects of a well-rounded fitness routine, they are not the primary purpose of warm-ups. The main goal is to ensure that the body is physically prepared for the demands of the activity to follow, making the increase in heart rate and blood supply the most critical objective during this phase.
