Which of the following would serve as a general warm-up for a moderate run?

A general warm-up is designed to gradually increase the heart rate and prepare the body for more intense physical activity. In the context of a moderate run, the ideal warm-up should enhance circulation and increase muscle temperature, leading to optimal performance while minimizing the risk of injury.

Jumping jacks effectively elevate the heart rate and warm up major muscle groups. This dynamic movement incorporates both the upper and lower body, increasing blood flow and preparing the muscles for the running activity. By engaging multiple muscle groups in a rhythmic manner, jumping jacks help to ready the body for the upcoming demands of a moderate run.

While other options, such as dynamic stretching and light jogging, can also be effective warm-up activities, jumping jacks uniquely combine cardiovascular engagement with muscular activation. Static stretching, on the other hand, does not adequately prepare the body for the more dynamic and demanding activity of running, as it can momentarily decrease muscle power and performance.
