In short: the serve breaks down in three predictable spots. An inconsistent toss, a hand that is out of place at the setup, and lost speed from missing pronation. Three short drills, a few minutes a day, will lift your first-serve percentage faster than any change of gear.
Most players think a weak serve is about power. It is not. A good serve is built on a precise sequence, and most mistakes happen before the racket ever meets the ball. Fix the early stages and the speed shows up on its own.
Drill 1: a consistent toss
The toss is the foundation. If the ball lands somewhere different every time, everything after it falls apart. Stand near a wall, toss the ball without hitting it, and let it drop. Mark a spot on the floor about half a meter forward and slightly to the right of your front foot, then aim for it twenty times in a row.
- Hold the ball in your fingertips, not your palm, so you control the release.
- Raise your arm straight up and release at full height, not with a throwing motion.
- Do not put spin on the ball. A flat toss is predictable.
- Check that the ball keeps landing on the same marked spot.
- Twenty reps a day for three weeks, and the difference is clear.
Drill 2: the trophy position
Right after the toss, your body should reach the trophy position: the racket arm bent with a high elbow, the tossing arm stretched up toward the ball. This is where energy is stored before the launch. Practice it in slow motion in front of a mirror, hold the pose for two seconds, and check that the elbow sits at shoulder height.
Once the position feels natural, link it to the toss. Toss, reach the trophy, stop. Do not carry on into the hit at this stage. You are building movement memory, not scoring points. If you are still weighing up how to choose a tennis racket for your level, remember that a racket that is too heavy makes reaching this position on time much harder.
Drill 3: racket drop and pronation
This is where the speed comes from. From the trophy position the racket head drops down behind your back, then an acceleration wave finishes in pronation: the forearm rotates so the racket turns inward at the moment of contact. That single move separates a fast flat serve from a slow push. Practice it without a ball. Hold the racket above your head, let the head drop, and rotate your forearm as if you are screwing in a light bulb.
Pronation has to stay loose. If you tighten the wrist, the racket will not turn over and the speed is gone. Professional references on the tennis serve describe it as the most technically complete and demanding shot in the game, and for good reason.
Put them together in order
Run the three drills in sequence, because each one builds on the last. There is no point chasing speed before the toss is stable. Five minutes per drill is enough, but never skip the shoulder warm-up first, since repeated serves on a cold shoulder are a reliable way to get hurt. New to racket sports altogether? The same patience pays off in padel for beginners, where footwork and setup matter more than raw force.
Grab a basket of balls, pick one drill for today, and repeat it until the movement feels automatic. Only then move to the next.
