The consequences of not warming up before exercise can lead to increased risk of injuries such as strains, sprains, and muscle tears. Without proper warm-up, muscles and joints are less prepared for physical activity, potentially resulting in muscle stiffness and decreased performance. Additionally, a lack of warming up may hinder cardiovascular efficiency, causing excessive fatigue early in workouts. Incorporating effective warm-up routines enhances blood flow, increases muscle temperature, and prepares the body for the intensity of exercise, promoting a safer and more productive workout experience.
