Which area of the court is the libero restricted from entering?

The libero is a specialized defensive player in volleyball who is primarily responsible for receiving serves and playing in the back row. A distinctive feature of the libero’s role is the restriction from entering the front row. This is because the libero is not allowed to attack the ball above the net height, which is a key part of playing in that area. By keeping the libero positioned exclusively in the back row, the rules maintain the competitive balance and strategic dynamics of the game. This restriction helps to define the role of the libero and ensures that teams can utilize this defensive specialist without altering the fundamental offensive capabilities of their lineup.

In contrast, the back row, service area, and center circle are areas where players, including the libero, may freely operate within the confines of the game rules. The service area is specifically designated for serving, while the center circle is typically where players gather for the beginning of sets and at other stoppages.
