In what position is the server in when they serve?
There is lots of different ways but a good way is to stand sideways and holding the ball about to your belly button and putting your hitting arm up. Your opposite food is in front of the other.
Generally speaking, in the game of volleyball, the server is permitted to serve if their team receives the point. If the server does not serve the ball inside the court or over the net, the opposing team receives the point and serve. If the server's team keeps winning points, the same server will continue to serve the ball.
Yes, the libero can serve in volleyball. However, they can only serve for one position. Once the libero serves in a particular position in a game that is the only position where the libero is allowed to serve. However, the libero is not required to serve in that position for all subsequent rotations.
