The serve is the only shot in table tennis you have complete control over — no opponent, no pressure, no incoming spin to read. That makes it the highest-return thing you can drill by yourself, and yet most players barely touch it. Here are three drills that pay off fast.
Drill one: the target box. Lay a sheet of paper or a ball tub in the far corner and serve short to it, over and over, aiming to make the second bounce die right on the edge. Short, low serves that don't leap off the table are the ones opponents can't attack.
Drill two: same motion, different spin. Serve heavy backspin, then use the exact same arm swing to produce almost no spin. If your motion looks identical, your opponent can't read it — and the free points start rolling in as they push your no-spin ball into the net.
Drill three: serve and pounce. Serve short, then immediately step in as if attacking the return. Building the habit of moving after your serve means you're never caught flat-footed on the third ball, which is where most points are actually won.
Fifteen focused minutes a session and your serve stops being a way to start the point — it becomes a way to end it.
