What is the primary purpose of warm-up exercises?

The primary purpose of warm-up exercises is to prepare the body for activity and reduce injury risk. During a warm-up, the body gradually increases its heart rate and core temperature, which enhances blood flow to muscles and improves flexibility. This physiological transition helps the body adjust to the demands of physical activity, reducing the likelihood of strains and sprains that can occur if muscles are suddenly engaged in intense activity without a proper preparatory phase.

Additionally, warm-ups can enhance joint mobility and stimulate the nervous system, which can improve coordination and performance during the main workout. While other options, such as increasing muscle mass or burning calories, might occur as a result of engaging in a fitness routine, they are not the main benefits associated with warm-up exercises. A cool-down serves a different purpose, focusing on gradually reducing heart rate and aiding in recovery after exercise, which further emphasizes the distinct role of warming up prior to more vigorous activities.
