What is a key benefit of performing warm-ups before a workout?

Performing warm-ups before a workout primarily enhances circulation and flexibility, making this the key benefit. Warm-ups prepare the body for physical activity by gradually increasing the heart rate and promoting blood flow to the muscles. This increased circulation ensures that the muscles receive more oxygen and nutrients, which can improve performance and reduce the risk of injury during the actual workout.

Additionally, warm-ups improve flexibility by gradually stretching the muscles and tendons, which enhances their range of motion. This allows for better performance during physical activities and helps to prevent strains and sprains. By incorporating a proper warm-up routine, athletes and individuals can prepare their bodies more effectively, leading to safer and more efficient workouts.
