What is bears cheerleader?

As an AI language model, I cannot provide information on Bears cheerleaders specifically. However, professional cheerleading squads, such as those for NFL teams, are highly competitive to join and require rigorous training and fitness. Cheerleaders perform at games, events, and charitable activities to engage with and motivate the crowd, often incorporating dance, tumbling, and stunts. They also undergo extensive public speaking and media training to represent their team and sport effectively.
