A pre-exercise warm-up is crucial for preparing the body for physical activity. It helps increase muscle temperature, improving flexibility and range of motion, which can prevent injuries. Additionally, warm-ups enhance blood flow to the muscles, ensuring they receive adequate oxygen and nutrients during exercise. Psychological readiness is also addressed, as warm-ups help focus the mind on the forthcoming activity. Incorporating dynamic stretching and sport-specific movements in a warm-up routine can optimize performance and create a safer workout environment.
