Dynamic stretching is significant in warm-ups because it prepares the body for physical activity by increasing circulation and improving range of motion. Unlike static stretching, dynamic stretches incorporate movement and mimic the activity to be performed, which enhances muscle activation and prepares the nervous system for performance. Incorporating dynamic stretches can help reduce the risk of injuries and improve overall workout efficiency by activating key muscle groups. This type of warm-up is essential for optimizing performance and readiness for high-intensity activities.
