What are four illegal hits in a game of volleyball?

Answer 1

Illegal hits in volleyball:

-Catching or holding the ball

-Hitting the ball underhand with open palms

-Throwing the ball

-Changing the direction of the ball

There is also a thing called a double hit, which is generally called on for setters, when the ball hits their hands at a slightly different time while setting the ball. However, double hits are legal on a team's first hit, but not on subsequent hits.

Also, contacting the ball with any part below the waist is now considered legal.
