Which of the following should be avoided in a warm-up routine?

Static stretching should be avoided in a warm-up routine because it can temporarily decrease muscle strength and power, making it less effective for preparing the body for intense physical activity. During a warm-up, the focus should be on activities that increase blood flow, elevate heart rate, and enhance muscle elasticity. Dynamic stretching, light cardio exercises, and mobility drills are all effective components of a warm-up as they promote muscle activation and improve range of motion, which can contribute to better performance and reduced risk of injury during subsequent exercise. Static stretching, on the other hand, is generally more beneficial as part of a cool-down routine after the workout, where the goal shifts to improving flexibility rather than preparing the body for movement.
