What should players avoid doing while serving?

Players should avoid stepping on or over the end line while serving because this action constitutes a foot fault. In volleyball, the server must maintain their position behind the end line until the ball has been hit and is in motion. If a player steps on or crosses the line before the ball is struck, the serve is deemed illegal, resulting in a loss of serve for their team. This rule is in place to ensure fairness and maintain the integrity of the game, allowing both teams the opportunity to engage in play without disruption.

The other actions, while they may have their significance in terms of good sportsmanship or focus, do not directly violate the serving rules as emphatically as a foot fault does. For instance, hitting the ball with both hands can lead to a violation under certain circumstances, but it primarily pertains to how the serve is executed. Similarly, while making noise or looking at the audience may affect a player’s concentration, these actions do not impact the legality of the serve itself.
