I love volleying the ball.
I feel that it rushes the opponent and puts them under pressure.
Most club players only volley when the ball comes to them but I encourage my pupils to “hunt” for volleys.
Obviously, not every single shot but at last 5 more volleys per game than they normally play.
But number of volleys alone don’t win matches.
The volleys have to be good. Not necessarily winners, but a shot that poses a problem for the opponent.
Your first step is to practice volleys alone, then with a partner and then within practice games.
Keep you swing short and firm.
The next time you play, try to hit a few crosscourt volleys off weak straight drives. Aim for the sidewall behind the service box about a racket’s height from the floor.
If nothing else, “hunting” for volleys will make you more proactive.
