What should be the focus of warm-up exercises in group classes?

The primary purpose of warm-up exercises in group classes is to increase heart rate and prepare muscles for activity. This physiological preparation is essential as it gradually elevates heart rate and blood flow to the muscles, enhancing the delivery of oxygen and nutrients while also helping to increase muscle temperature and flexibility. By focusing on these aspects, participants reduce the risk of injury and improve their overall performance during the main workout.

While social interaction, skills evaluation, and minimizing the need for a cool-down are elements that can occur in a class setting, they do not address the critical physiological needs that a proper warm-up fulfills. Engaging participants socially or evaluating skills may enhance the class experience but should not detract from the key objective of effectively preparing the body for physical activity.
