Most tennis advice arrives as a slogan. Bend your knees. Follow through. Get the racket back early. None of it is wrong, and almost none of it is useful on its own, because a slogan tells you what a good player looks like without telling you what a good player is trying to do. This notebook takes the opposite approach. Every page here starts from a mechanical or tactical problem — the ball is arriving too fast, the court is too slow, the string bed is too stiff — and works forward to the adjustment that solves it.
It is written for the improving club player: somebody who already rallies comfortably, who plays a match most weeks, and who has reached the point where more hours of the same practice stop producing more wins. If that describes you, the ceiling is usually not effort. It is that two or three specific ideas have never been explained clearly enough to act on.
What is covered here
The notebook is organised into four groups, and the pages within each are meant to be read in any order.
- The ground rules. Scoring and the rules that actually decide points, and how court surfaces change the game — the two pieces of context that make every technical decision below make sense.
- Equipment. Choosing a racket by the four numbers that matter, and strings and tension, which is where most players are leaving the largest free improvement on the table.
- Strokes. The forehand, the backhand in both its one- and two-handed forms, and the serve.
- Movement, tactics and durability. Footwork and recovery patterns, doubles positioning, playing in heat and humidity, and conditioning and injury prevention.
There is also a glossary for the vocabulary that coaching conversations assume you already have.
The three ideas the whole notebook rests on
1. Height over the net is not a compromise
Club players are taught to hit low over the net because low looks aggressive. In practice, net clearance is the cheapest error-reduction available. A ball passing two feet over the net and one passing six inches over it land in almost the same place if the second has less topspin — but the six-inch ball has perhaps a third of the margin. Raising your average clearance by a foot and adding the spin to bring the ball down is not defensive. It is how depth is produced safely.
2. Your contact point is a consequence of your feet
Nearly every stroke fault that gets diagnosed as a swing fault is a spacing fault. A late forehand is usually a player who took one large step when four small ones were needed. This is why the movement page sits alongside the stroke pages rather than after them: adjusting the last three steps fixes more groundstrokes than adjusting the takeback ever will.
3. Equipment should match the swing you have
The racket and string setup you can play your best with is the one that suits your current swing speed and swing path, not the one used by whoever you enjoy watching. A player with a compact, flat swing and a player with a long, brushing swing need close to opposite setups. The racket and string pages set out how to work out which you are.
Where the authoritative answers live
This is a notebook, not a governing body. Where a question has an official answer — the dimensions of the court, what constitutes a let, the specifications a ball must meet — the definitive source is the International Tennis Federation, which publishes the Rules of Tennis and the technical standards for balls, rackets and court surfaces. For coaching frameworks and player-development material, the instruction libraries published by the United States Tennis Association and the Lawn Tennis Association are both free and unusually well organised. Anything on this site that contradicts those sources is wrong, and they win.
How to use it
Pick the single page that addresses the thing that most often costs you points, read it once, and take exactly one idea onto court. Change one variable at a time and give it three sessions before you judge it. Most players who plateau do so because they change four things a month and can never attribute the result — a habit that feels like diligence and functions like noise.
If you are not sure where to start, start with strings and tension. It is the shortest page here, it costs the least to act on, and it is the one that changes the most for the most people.
