Warming up before intense workouts is significant as it prepares the body for physical activity by gradually increasing heart rate and blood flow to muscles. This process enhances muscle elasticity and reduces the risk of injuries by ensuring that muscles and joints are adequately prepared for stress. A proper warm-up can also improve performance by enhancing neuromuscular efficiency and mental focus. Activities like dynamic stretching and low-intensity cardio are common components of warm-up routines, setting a solid foundation for more strenuous exercise.
