The volley starts off being the simplest stroke in tennis because you don't have to do any work. Just hold the racquet firmly with the head pointing upwards and the ball will rebound back over the net.

There are all kinds of volleys: punch, drop, angled, drive, jump & evade...but with all this variety there are some don'ts that every tennis player should avoid.

Another "don't" is to drop the wrist to play a low shot.

The racket should be lowered to meet the ball but the angle between the wrist and the racket should still remain constant.
