The warm-up mistake almost every tennis player makes

The scene is the same at virtually every tennis club in the country. Two players walk onto court, drop their bags, unzip a can of balls, and start hitting from the baseline. Within thirty seconds they are rallying at something close to full pace. There has been no warm-up. Or rather, there has been a warm-up, but it consisted entirely of the first few minutes of hitting, which is a bit like warming up for a car crash by adjusting the rear-view mirror.

The other version is marginally better but no less theatrical in its self-deception. The player arrives a few minutes early, stands by the fence, and performs a sequence of static stretches that they have been doing since school: touch the toes, pull the arm across the chest, hold the quad stretch for ten seconds with the expression of someone who has just remembered they own a body. It feels responsible. It looks like preparation. In terms of what it actually does before an hour of explosive lateral movement, rotation and impact, it accomplishes remarkably little. You could get a similar physiological benefit from standing very still and thinking about exercise, which, in fairness, is what most of the stretching amounts to.

The warm-up is probably the most skipped, most misunderstood and most undervalued five minutes in club tennis. And the cost of getting it wrong, or not doing it at all, is not just an increased risk of pulling something. It is a worse standard of tennis from the very first point.

The static stretching problem

The idea that you should stretch before exercise is so deeply embedded in sporting culture that questioning it can feel almost heretical. And stretching is not without value. But the distinction between static stretching and dynamic movement preparation is one that much of the research over the past two decades has made increasingly difficult to ignore.

Static stretching, the kind where you hold a position for fifteen to thirty seconds, is designed to improve flexibility over time. As a pre-activity intervention, the evidence suggests it does not reduce injury risk in any meaningful way and may temporarily reduce the muscle's ability to produce force. For a sport that requires explosive first steps, rapid deceleration and powerful rotation, spending five minutes putting muscles into a passive, lengthened state before asking them to do the opposite is rather like loosening all the bolts on a car and then driving it to a racetrack. You have not prepared the machine. You have mildly sabotaged it.

This does not mean stretching has no place. After a session, when the goal is recovery and maintaining range of motion, static stretching is perfectly appropriate. But before a session, the body needs something different. It needs to be switched on, not stretched out.

What switching on actually means

A tennis match demands an unusual combination of physical qualities. You need to sprint short distances and stop abruptly. You need to change direction at speed, often on a single leg. You need to rotate your trunk through a wide range under load. You need your shoulders to produce and absorb force repeatedly at high speed. And you need to do all of this from a cold start, often within the first few points of a match.

A good warm-up prepares the body for specifically these demands. Not in a general "raise the heart rate" sense, though that matters, but in a targeted sense: the muscles and movement patterns that tennis is about to ask for need to be activated and rehearsed before the first ball is struck.

The glutes are a good place to start, and for most club players, the most important. The gluteal muscles are the primary drivers of lateral movement, deceleration and hip rotation. They are also, in a population that spends most of the day sitting, chronically underactive. The average club player's glutes have been switched off since approximately 9am, pressed into an office chair like two forgotten cushions, and are now being asked, with no notice whatsoever, to produce explosive lateral force on a hard court. A player who walks onto court without waking them up is asking the knees, the lower back and the ankles to compensate for what the biggest muscles in the body are not yet doing. That compensation is where injuries live.

Lateral band walks, bodyweight squats, lunges with rotation, and single-leg glute bridges are not glamorous exercises. Nobody has ever looked heroic doing a banded side-step in a car park. They take three to four minutes. But a player who has done them before stepping on court will move differently from the first point: lower, more stable, more willing to push off and change direction with confidence. The glutes are firing. The foundation is there.

Shoulders and the rotation chain

The shoulder is the other area that most warm-ups neglect entirely. Players will hit gentle forehands to "warm up the arm," but the rotator cuff, the group of small muscles that stabilises the shoulder joint during the serve and overhead, does not get meaningfully prepared by rallying. It gets prepared by specific activation: light resistance band work through external and internal rotation patterns, slow arm circles with intention, and movements that take the shoulder through the range it is about to use at speed.

This matters particularly for the serve, which is the most violent action in tennis and typically the one that gets the least physical preparation. A player who serves at full pace in the first game without having activated the rotator cuff is relying on cold, unprepared tissue to manage forces that would test it even when warm. It is the muscular equivalent of asking someone to sprint the moment they wake up, except the someone in question is a small group of muscles that you have never thanked, possibly cannot name, and will not think about until one of them tears. Over time, this is how the slow accumulation of shoulder strain begins. Not from one bad serve, but from hundreds of first serves hit before the shoulder was ready for them.

The same principle applies to the thoracic spine, the mid-back region that drives trunk rotation on every groundstroke. A few controlled rotational movements, a thread-the-needle stretch, or simply swinging the arms across the body with intention can take the thoracic spine from stiff and resistant to mobile and responsive. The difference in how the first few forehands feel is noticeable. The difference in how the mid-back feels the next morning is often more so.

Preparing to move, not just to hit

There is a revealing bias in how most players think about warming up, which is that they think about it entirely in terms of hitting. The warm-up rally, the gentle serves, the first few volleys. All of these prepare the hand and the eye, but they do almost nothing to prepare the body for what tennis actually demands most: movement.

Tennis is not a hitting sport that involves some movement. It is a movement sport that involves some hitting. The ability to get into position, set the feet, transfer weight and recover is the foundation on which every shot is built. And yet the movement system, the lateral agility, the deceleration, the first-step explosiveness, is the part that receives the least preparation before play.

A two-minute movement sequence before hitting, even something as simple as lateral shuffles, carioca steps, short sprints with a deceleration, and a few split-step rehearsals, primes the neuromuscular system for the demands it is about to face. The feet are quicker from the first point. The stops are cleaner. The timing of the split step, which is itself a product of physical readiness as much as habit, is sharper. Players who do this consistently describe the same thing: they feel like they are in the match from the start rather than spending the first three games finding their movement.

The timing dividend

There is a less obvious benefit to a proper warm-up that goes beyond injury prevention and physical readiness, and it relates to the quality of the tennis itself. Shot timing in tennis is not purely a hand-eye phenomenon. It is a whole-body phenomenon. The timing of a forehand depends on the player being in position, balanced, and physically prepared to transfer weight at the right moment. When the body is cold, stiff and reactive rather than primed and ready, the timing suffers, and the player attributes it to rustiness or a slow start rather than to the fact that their body was not ready to play tennis when the match began.

The first set is where most club matches are decided, and it is also the period where the physical cost of a poor warm-up is highest. A player who arrives on court already activated, already moving well, already physically switched on has a meaningful advantage over an opponent who is spending those opening games trying to find their timing. It is not a fitness advantage. It is a readiness advantage, and it is available to anyone willing to invest five minutes before walking through the gate.

Five minutes that change the session

The reluctance to warm up properly is understandable. Court time feels precious. The temptation to start hitting immediately is strong, and the warm-up can feel like dead time when all you want to do is play. But the trade is a poor one. Five minutes of targeted preparation, glutes, shoulders, rotation, movement, buys you a better first set, a lower injury risk, and a body that is capable of doing what your brain asks it to from the very first ball.

If you want to make this even simpler, buy a resistance band. A light one. They cost less than a can of balls, weigh almost nothing, and roll up small enough to fit into even the slimmest tennis bag, wedged between your spare grip and the banana you forgot about last Thursday. All Court is fortunate enough to get into the players' areas at the odd Grand Slam, and the one piece of equipment you will see in every single bag, on every single chair, draped over every single physio bench, is a resistance band. Every tour pro on the ATP and WTA owns one and uses it. Not because they are doing anything exotic with it, but because five to ten minutes of banded work before a match is the simplest way to switch the body on.

A practical sequence with a band might look something like this: lateral band walks, ten steps each direction, to fire up the glutes and hips. Banded external rotations, ten each arm, to wake up the rotator cuff. Pull-aparts at chest height, fifteen reps, to activate the upper back and posterior shoulder. A few banded squats to connect the legs to the trunk. Then a set of banded lateral shuffles at pace to bridge the gap between activation and movement. The whole thing takes five to ten minutes, requires no space beyond a few feet of corridor or car park, and the difference it makes to how you feel from the first ball is disproportionate to the effort involved.

The mistake is not that players do not care about their bodies. Most do, in the way that people care about their roofs: with complete confidence that everything is fine, right up until it starts raining indoors. The warm-up has been framed as a tedious obligation rather than what it actually is: the cheapest, simplest performance advantage available in the sport. One resistance band and five minutes. That is the entire ask.
