Warm-up exercises are critically important before engaging in physical activity as they prepare the body for increased demands. These exercises enhance blood flow to muscles, elevating both heart rate and body temperature. A proper warm-up reduces the risk of injury and improves overall performance during the workout. Additionally, warming up increases flexibility and range of motion, enabling more effective movement patterns. Failing to include adequate warm-ups can lead to muscle strains and other injuries, emphasizing the importance of this preparatory phase in any exercise regimen.
