Which of the following is NOT a recommended way to increase interaction among participants in a group fitness class?

Organizing happy hours after class is not considered a recommended way to increase interaction during the fitness class itself. While social gatherings outside of the class can foster community and camaraderie, the primary goal of a fitness class is to focus on physical activity, engagement, and support among participants during the workout. The other options, such as using partner-based exercises, encouraging group discussions, and incorporating team challenges, actively promote interaction during the class by engaging participants in collaborative and social ways within the context of the workout. These methods directly enhance the experience and build connections among individuals while they are participating in fitness activities.
