Which of the following is NOT a benefit of warming up before exercise?

The rationale behind choosing "instant weight loss" as the answer lies in understanding the purpose and effects of warming up before exercise. Warming up effectively prepares the body for physical activity by gradually increasing the heart rate and blood circulation, leading to more efficient oxygen delivery to the muscles. Additionally, it helps to enhance flexibility, reduce muscle stiffness, and improve overall performance, thereby contributing to injury prevention and preparation for the workout.

While increased blood flow to muscles, reduced risk of injury, and enhanced mental preparation are all recognized benefits of a proper warm-up, instant weight loss is not a direct or immediate outcome of this practice. Weight loss occurs over a sustained period through a caloric deficit and exercise, rather than as an instantaneous effect from warming up. Therefore, it does not belong among the benefits typically associated with pre-exercise warm-ups.
