What is a necessary component that group fitness classes should start with?

A warm-up is a necessary component that group fitness classes should start with as it prepares the body for the upcoming physical activity. This phase gradually increases heart rate, enhances blood flow to muscles, and raises body temperature, all of which help reduce the risk of injury. A proper warm-up also improves flexibility and mobility, allowing participants to perform movements safely and effectively.

Furthermore, engaging in a warm-up helps mentally prepare participants for the workout. It promotes a transition into the fitness session, making individuals more focused and less likely to sustain injuries during more intense parts of the class. Therefore, incorporating a dedicated warm-up segment is essential for creating a safe and effective group fitness experience.
