A proper warm-up before exercising provides several immediate benefits, most notably improved performance and reduced risk of injury. When you engage in a warm-up routine, your body gradually transitions from a state of rest to one of activity. This process includes increasing blood flow to the muscles, which enhances oxygen delivery and nutrient supply necessary for energy production.

Additionally, warming up raises your body temperature, which can improve muscle elasticity and joint mobility. This is crucial because warmer muscles are less prone to strains and sprains, thus significantly reducing the risk of injury. The combination of these physiological changes leads to better overall performance during the main workout, enabling you to execute movements more effectively and with greater efficiency.

In contrast to the correct option, choices that suggest negative outcomes, such as increased risk of injury or decreased heart rate, highlight misconceptions about warming up. A warm-up should not focus solely on strength training nor lead to a decrease in heart rate; instead, it is an essential activity that prepares the entire body for exercise by enhancing performance and safety.
