The serve is the only shot in tennis you have complete control over. No one is hitting back at you. The ball isn't moving until you throw it. You have time.
And yet it's the shot most players dread.
When students come to me frustrated with their serve, they've usually already diagnosed the problem: my toss is inconsistent. Nine times out of ten, they're wrong.
What I actually see
I've watched thousands of service motions. Here's the real breakdown of what goes wrong:
Grip: Most recreational players use an Eastern forehand grip on the serve. It feels natural. It produces flat, pushable serves with no spin and limited power. A continental grip — where the base knuckle sits on bevel 2 — enables pronation, slice, kick, and real pace. Most people resist this because it feels weaker at first. It is weaker at first. That's fine.
Trophy position: Players rush through the trophy position — the moment of maximum coil before the swing begins. When you rush it, you lose the kinetic chain. The legs don't load, the shoulder doesn't drop, the racket doesn't fall into the back-scratch properly. Slowing down the start to speed up the contact point is a lesson I repeat constantly.
Contact point: Players making contact too far forward (toward the net) or too close to their body can't pronate properly. The ideal contact point is slightly in front of the lead shoulder, with the arm almost fully extended. Most beginners contact the ball where they can see it easily — which is usually too far back and too low.
The toss: Yes, the toss matters. But it's usually the last thing I change, not the first. A player with a perfect grip, coil, and contact point can work around a slightly imperfect toss. A player with a broken grip can't compensate no matter how perfect the toss is.
The drill I use most
I call it the fence drill. Player stands about a foot from the fence, faces it, and serves in slow motion with zero concern for where the ball goes. The fence stops the serve so there's no pressure about landing it in the box.
What it reveals: everything. The grip, the contact point, the pronation. Without the net or the service box to worry about, players can focus on the motion itself.
After ten minutes at the fence, most people's serves look meaningfully different. Better. That's when we move back and add the full court.
Patience is the skill
Fixing a serve takes months, not sessions. The motion has to be unlearned before it can be relearned. Players who accept this improve. Players who want it fixed by next Tuesday usually make it worse.
I've rebuilt my own serve twice. The second time, I served worse for three months before I served better. That's the process.
Worth it.
