What term describes the process of warming up before exercise?

The term "warm-up" specifically refers to the set of activities or exercises undertaken prior to engaging in more intense physical activity or exercise. This process is essential for increasing the heart rate, enhancing blood flow to the muscles, and gradually raising body temperature, all of which help to prepare the body for the physical demands to come. A proper warm-up can improve performance and significantly reduce the risk of injuries by increasing flexibility and readiness of the muscles and joints.

In contrast, options like "cool down" refer to activities performed after exercise to help the body transition back to a state of rest. "Activation" may suggest initiating bodily movement but lacks the specificity needed to convey the nuances of a warm-up designed to prepare muscles and cardiovascular function before a workout. "Preparation" is a more general term that does not distinctly capture the physiological aspects and objectives of a structured warm-up routine. Thus, the choice of "warm-up" accurately encapsulates the process aimed at priming the body for exercise.
