To develop a kick serve in tennis, you need to master four things: a continental grip, a toss placed slightly behind your head and toward your non-dominant shoulder, a racket swing that brushes upward across the back of the ball from roughly 7 o’clock to 1 o’clock on an imaginary clock face, and strong leg drive that pushes the whole body upward through contact. The result is a ball that clears the net in a high arc, dives sharply into the service box, and then bounces up high and moves sideways, giving your opponent very little time to attack. It is widely considered the hardest shot to learn in tennis, but it is also one of the most valuable weapons any serious player can add to their game.
What Is a Kick Serve and Why Is It So Effective in Tennis?
A kick serve in tennis is a serve that combines topspin and sidespin to produce a ball that arcs high over the net, lands steeply in the service box, and then bounces up sharply and moves sideways. The Tennis Tribe coaching resource describes the kick serve’s angle of rotation as approximately 45 degrees between topspin and sidespin, which is what creates both the high bounce and the sideways kick after it lands. That combination makes it extremely difficult to attack. A flat serve that lands in the box usually bounces to around waist height. A properly executed kick serve, according to physics research from the Tennis Warehouse University, needs to land in the service box at speed and at a relatively steep angle to bounce up to shoulder height or above as it crosses the baseline.
The kick serve is the most reliable second serve at every level of competitive tennis. According to Wikipedia’s detailed coverage of the serve in tennis, second serves almost always have slice, topspin, or kick on them because spin makes the ball less likely to land in the net or out of bounds compared to a flat serve. A confident second serve is one of the most important weapons in the game. Former world No. 1 players and coaches have pointed to a weak second serve as a critical factor that limits a player’s ability to win titles at the highest levels of the sport.
Players training at Hillcrest Tennis Camp near Cresthaven Drive in North York often work on the kick serve specifically because it transforms the second serve from a defensive necessity into an attacking weapon. When your second serve bounces to shoulder height and kicks away from the returner, they can no longer step in and attack it confidently. That changes the entire dynamic of your service games.
What Grip Is Best for a Kick Serve?
The best grip for a kick serve is the continental grip, also known as the chopper grip, though some players shade slightly toward the eastern backhand grip for extra spin. UTR Sports’ kick serve guide recommends using the continental grip because it keeps all serving options open and supports the pronation your forearm needs through contact. To find the continental grip, hold the racket handle as if you are going to chop wood with the edge of the frame, with your base knuckle resting on the second bevel of the handle.
A common beginner mistake is using a forehand grip to try to serve. TennisTraining-Online’s kick serve coaching guide confirms that most adult players first learn to serve with a forehand grip because quick success comes easily with it, the racket face naturally points toward the target and getting the ball in is simple. But a forehand grip makes it physically impossible to brush up the back of the ball and generate the topspin needed for a kick serve. The continental grip is non-negotiable. It feels awkward at first, but FeelTennis coaching research notes that it takes roughly 3 to 6 months to feel fully comfortable with the continental grip on the serve, and the long-term power and spin benefits are well worth the early discomfort.
Where Should You Toss the Ball for a Kick Serve?
For a kick serve, you should toss the ball slightly behind your head and toward your non-dominant shoulder. For right-handed players, that means the toss goes over the left shoulder, roughly at the 11 o’clock position above your body if you picture yourself on a clock face. For left-handed players, the toss goes over the right shoulder. This is the single most important technical difference between a kick serve and a flat or slice serve, and getting it wrong makes everything else impossible.
The Tennis Tribe’s coaching breakdown explains that when tossing for the kick serve, you hold onto the ball slightly longer than normal, which naturally pushes it behind your head and over the non-dominant shoulder. The ball should also be allowed to fall slightly lower before contact than on other serves. Letting the ball drop about 30 centimeters lower allows the racket to approach the ball at roughly a 45-degree angle, sideways rather than fully vertical, which is the position needed to brush up the back of the ball and produce topspin.
A very high toss also helps generate topspin on the kick serve. Physics research from Tennis Warehouse University explains that a falling ball is equivalent to a rising racket in terms of topspin generation. The higher the toss, the more the ball is falling at contact, which makes it easier for the racket to brush up the back of the ball at a steep angle and produce the spin needed to kick the ball high off the bounce.
An important note on disguise: UTR Sports’ kick serve coaching resource stresses that you should practice making your kick serve toss look as similar to your flat serve toss as possible from a distance. Exaggerating the toss too far to the side tells the returner exactly what is coming before you even hit the ball, which removes most of the serve’s tactical value.
How Do You Brush the Ball to Create Topspin on a Kick Serve?
To create topspin on a kick serve, you brush the racket upward across the back of the ball from 7 o’clock to 1 o’clock on an imaginary clock face placed behind the ball. This motion makes the racket strings move steeply up the back of the ball, generating the forward spin that causes the ball to dive sharply into the court and then kick high off the surface after the bounce.
My Tennis Life’s kick serve coaching guide describes the contact motion as brushing up and across the ball while avoiding the flat through-the-ball motion used on a flat serve. The key physical cue is to think “up the mountain” rather than “through the wall.” Your chest should be rising as you swing, your legs are driving you upward off the ground, and the racket head is moving steeply up the back of the ball rather than forward through it.
GoTennis coaching resources add that to impart sidespin alongside the topspin, you angle the racket face inward slightly at contact, turning the face a little to the side while still swinging primarily upward. This simultaneous combination of topspin and sidespin is what produces the “kick” after the bounce, where the ball does not just bounce high but also moves sideways, pulling the returner off the court or jamming them depending on the placement.
According to the ProdigyMaker coaching blog, the racket knuckles should be pointing essentially toward the sky as the racket moves up to the ball, with the palm facing partially downward toward the court. Many players swing upward with the palm facing the sky, which makes it physically impossible to create the spin needed for the kick serve. Getting the palm-down orientation correct is one of the most important technical adjustments a player can make when learning this serve.
How Important Are the Legs and Body in a Kick Serve?
The legs and body are critically important in a kick serve. In fact, the serve is not primarily an arm shot. Research published in PMC on the biomechanics of the tennis serve confirms that the serve is the most energy-demanding motion in the sport, accounting for 45 to 60 percent of all strokes performed in a match. Biomechanical research on serve loading published in Tennisresor’s serve analysis guide estimates that approximately 55 percent of the energy in a serve originates from the legs and torso, transmitted upward through the core to the shoulder and arm. When this kinetic chain breaks down, the shoulder and elbow have to compensate and carry more load, which increases injury risk.
For the kick serve specifically, strong knee bend and explosive upward drive from both legs is essential. The Tennis Tribe’s coaching guide confirms that you need to explode upward from the legs during the kick serve, not forward. On a flat serve, you drive your body weight into the court. On a kick serve, you drive upward, which helps get the racket above and behind the ball at the steeper contact angle needed for topspin.
Research on serve biomechanics published in PMC by the National Institutes of Health found that improper knee flexion during the serve significantly increases mechanical loads on the shoulder and elbow. A biomechanics study in the same publication found that serves performed without proper knee flexion increased loads on the shoulder and elbow by 17 to 23 percent compared to serves performed with correct knee flexion. For a kick serve, where you are already placing high demands on the shoulder through the arched back position, strong leg drive is not optional. It is what protects your arm by distributing the load across the whole body.
Is a Kick Serve Harder on Your Shoulder Than a Flat Serve?
A kick serve places similar shoulder loads to a flat serve, but the back arch required to toss the ball behind the head adds extra stress to the lower back. Biomechanical research on shoulder loading during the flat and kick serve, published in PMC, found that the mean compressive force applied to the shoulder during the forward swing was approximately 220 Newtons for both the flat serve and the kick serve, with no significant discrimination between serve types at the shoulder joint level. The study concluded that the repetitive long-term performance of either serve is what matters most for shoulder injury risk, not the serve type itself.
However, the lower back is a different story. Serve biomechanics analysis published in the Tennisresor serve guide states that kick serves with the racket head further behind the body can increase the risk of both shoulder and back injuries compared to flatter serves, because the back arch and twisting motion generates extra stress on the lumbar spine. Research published in PMC on musculoskeletal disorder risk during the tennis serve found that the loading and cocking phases of the serve were classified as “very high-risk activity” on the REBA ergonomic scoring scale, with mean scores above 11 out of a possible 15.
The best protection against injury on the kick serve is correct technique combined with strong leg drive. According to research published in PMC reviewing injury risk factors for the tennis serve, dominant shoulder rotation strength and internal rotation range of motion are among the most significant factors in reducing serve-related injury risk. A structured warm-up routine and targeted shoulder and core strengthening are also strongly recommended. Players learning the kick serve for the first time should build the motion gradually and never try to hit with maximum effort until the technique is comfortable and consistent.
Why Is the Kick Serve Particularly Hard on Junior Players?
The kick serve is particularly hard on junior players because the extreme back arch and lateral bending of the spine, combined with high training volumes, can put young vertebrae under stress they are not yet ready to handle. Research published in PMC on rotator cuff injuries notes that the topspin serve is commonly taught to junior tennis players because it clears the net reliably and lands in the service box safely, but adds that it should be used judiciously in younger players due to the potential risk of shoulder injuries. Biomechanical analysis of kick serve motion in junior elite players, published in Sports Medicine Open, found that lumbar joint reaction forces during the acceleration phase of the serve can be 3 to 40 times greater than those experienced during running.
Junior players at Hillcrest Tennis Camp in North York, who join from neighbourhoods across Willowdale, Bayview Village, and the Don Valley Village area, learn serve mechanics under careful supervision. Certified coaches build technique progressively, starting with the basic continental grip and toss positioning before adding the full kick serve motion, so that young bodies develop the right habits without being overloaded too early.
What Are the Most Common Kick Serve Mistakes?
The most common kick serve mistakes are using the wrong grip, tossing the ball too low or too far in front, swinging through the ball instead of brushing upward across it, failing to use leg drive, and losing balance during or after the serve. Each of these errors either removes the topspin, causes the ball to go into the net, or sends it long past the service box.
The wrong toss is the most frequently cited mistake. GoTennis coaching resources note that one of the biggest mistakes players make when attempting the kick serve is throwing the ball too low. When the toss is too low, the racket is fully extended at contact and can only swing forward through the ball, which produces a flat result rather than the upward brushing motion that creates topspin. Tossing slightly higher and letting the ball fall to the correct contact point gives the racket the chance to approach the ball from below and brush up the back of it.
Swinging through the ball rather than up and across it is the second most common error. My Tennis Life’s kick serve guide identifies this as “not getting enough topspin,” with the ball landing at waist height or lower rather than bouncing up sharply. The fix is to focus on the upward swing path, finishing high over the opposite shoulder, and to think of the swing as a steep upward brush rather than a forward punch.
Falling backward is another common problem. The Tennis Tribe coaching guide notes that many players fall off to the side or backward during the kick serve because the toss goes too far behind them and they lose their center of gravity. The fix is to practice landing in roughly the same spot you started from, keeping your balance through contact before moving forward into the court.
When Should You Use a Kick Serve in a Match?
You should use a kick serve in a match when you are serving a second serve, when you are facing an opponent with a weak or one-handed backhand, when you want to force the returner out of position on the ad side, when playing on clay, or when you are under pressure on an important point. The kick serve excels in all of these situations because its high bounce forces the opponent to hit a difficult shot above their comfortable strike zone.
The kick serve is perhaps most valuable on clay courts. WebTennis24 coaching resources confirm that on clay, the higher surface friction causes the ball to grip and kick up at a steeper angle than on other surfaces, making the already difficult bounce even more pronounced. Players from the Don Mills and Banbury-Don Mills areas who compete on clay during the spring and summer season will find the kick serve one of their most reliable tools for holding serve in long baseline rallies.
Against one-handed backhands, the kick serve is particularly dangerous. Analysis from TennisAbstract’s Match Charting Project data shows that servers target the backhand corner of one-handed backhand players on 47.3 percent of first serves and 40.9 percent of second serves, compared to 44.2 percent and 34.8 percent against two-handed backhand players. The reason is well established: a ball bouncing up to shoulder height or above into a one-handed backhand is one of the hardest returns in tennis to hit aggressively. The player has to lift the ball up further, the swing path becomes awkward, and the result is usually a defensive return that hands the server control of the rally.
The kick serve is also smart to use at break points and other high-pressure moments. My Tennis Life’s coaching guide confirms that at break points, the kick serve adds safety while still keeping your opponent on defense. You are not just hoping the ball goes in. You are hitting a serve with a large margin over the net that also produces a difficult bounce, which is the best possible combination under pressure.
Players who work on their serve through structured coaching, such as those in the adult group lessons program at Hillcrest Tennis Camp, learn how to deploy different serve types tactically rather than relying on just one option. A well-coached adult player who can place a flat serve wide, a kick serve to the backhand, and a slice serve into the body from the same basic motion is a genuinely difficult player to return against.
How Long Does It Take to Learn a Kick Serve?
It takes most players several months of focused practice to develop a reliable kick serve. The ProdigyMaker coaching article, written by a coach who competed on the ITF pro futures tour, calls the kick serve the hardest shot in the game to learn and says that even players who practice thousands of balls in their junior years often do not master it until their twenties without correct coaching. FeelTennis coaching notes that the basic continental grip alone takes 3 to 6 months to feel fully natural on the serve, and the kick serve adds additional layers of complexity on top of that.
With good coaching and a structured practice plan, the timeline can be shortened significantly. FeelTennis kick serve training recommends drilling the toss and brushing motion at least twice a week for 20 to 30 minutes, and states that players will see meaningful improvement in accuracy within a few weeks of consistent repetitions with the correct motion. The key is always to practice the correct motion, not just to hit balls over the net. Every repetition of a wrong swing pattern builds bad habits that take far longer to undo than it took to form them.
The kick serve progression from beginner to reliable match use looks roughly like this for a player who has never served with a continental grip before: 2 to 4 weeks to become comfortable with the continental grip, 4 to 8 weeks to produce consistent topspin from close range with correct brushing motion, 8 to 16 weeks to hit the kick serve reliably from the baseline with acceptable consistency, and 6 months or more to use it confidently in match play under pressure. These timelines come from practical coaching experience described in TennisTraining-Online’s kick serve development guide.
What Are the Best Drills to Develop a Kick Serve?
The best drills to develop a kick serve are the brush-against-fence drill, the knee-serve drill, the over-the-obstacle drill, and the cone target drill. Each isolates one component of the kick serve before combining them into the full motion.
The Brush-Against-Fence Drill
Stand close to a fence and slowly swing the racket upward in the kick serve brushing motion, making contact with the fence at the top of the swing. This drill gives you direct feedback on whether your racket is actually moving upward steeply through the contact zone rather than forward and flat. UTR Sports’ kick serve guide includes this as a foundational drill because it removes the complexity of the ball and lets you focus entirely on the swing path and brushing sensation.
The Knee-Serve Drill
Kneel on your back knee facing the net and serve from that position, using only your upper body to generate topspin. This drill isolates the shoulder, arm, and wrist motion needed to brush up the back of the ball, without the added complexity of leg drive and body rotation. UTR Sports recommends 30 brushing swings into a fence from the kneeling position as part of a complete kick serve warm-up session before hitting full serves.
The Over-the-Obstacle Drill
Place a taller-than-net obstacle, such as a ball cart or the netting between adjacent courts, a few feet in front of the service line. Hit kick serves from the service line, forcing yourself to arc the ball over the higher obstacle. FeelTennis coaching confirms this drill is highly effective because it exaggerates the need for height and upward swing path, training the player to generate more topspin by physically requiring the ball to clear a taller target.
The Cone Target Drill
Place cones in the ad and deuce service boxes, targeting the deep backhand corner, the T, and the body zone. Hit 10 kick serves to each cone, focusing on both clearing the net high and producing a high bounce rather than pace. UTR Sports’ coaching guide recommends tracking how many balls you hit to each cone across a session, which builds placement precision alongside spin consistency.
Young players working on the kick serve through the junior summer camp at Hillcrest Tennis Camp on Cresthaven Drive near Bayview Avenue and Sheppard run through exactly this kind of progressive drill structure under the supervision of certified coaches. Building the motion correctly from the start is far more effective than trying to correct a deeply ingrained wrong motion later.
Kick, Flat & Slice Serve Comparison: Best Second-Serve Choice
The kick serve is the best option for second serves because it clears the net with the most margin while still producing a ball that is difficult to attack. The flat serve has very little margin over the net and requires near-perfect execution to land in the box reliably. The slice serve has more margin than the flat serve and stays low, but at club and recreational level the low bounce is easier to drive aggressively than a high-kicking ball above the returner’s shoulder.
| Serve Type | Spin Direction | Net Margin | Bounce Height | Best Used As | Strongest On |
|---|---|---|---|---|---|
| Flat Serve | Minimal | Very low | Waist height | First serve (power) | Hard / Grass |
| Slice Serve | Sidespin | Moderate | Low, skids wide | First serve (angles) | Grass / Hard |
| Kick Serve | Topspin + sidespin | Highest | Shoulder height+ | Second serve (reliability and pressure) | Clay / Hard |

According to TennisInstruction’s second serve coaching article, a good second serve is almost always a spin serve. The article points out that players whose second serves become attacking targets for opponents have historically won fewer titles than their first-serve ability might suggest, regardless of how big their first serve is. The kick serve, hit with enough topspin to produce a high bounce and enough sidespin to move the ball away from the returner’s backhand, is the standard second serve weapon at college and professional levels for very good reason.
Frequently Asked Questions
How Do You Improve Your Kick Serve in North York?
To improve your kick serve in North York, practice the brushing motion twice a week for at least 20 to 30 minutes using the fence brush drill and the knee-serve drill before moving to full serves from the baseline. FeelTennis coaching research confirms that consistent repetitions of the correct brushing motion, twice a week, will produce noticeable improvement in kick serve accuracy within a few weeks. Players training at Hillcrest Tennis Camp near the Cresthaven Drive and Bayview corridor in North York have access to certified coaches who can identify the specific part of the motion where the topspin is being lost and correct it directly, which is far faster than trying to troubleshoot alone.
How Long Does It Take to Learn a Kick Serve?
It takes most players 3 to 6 months of regular, focused practice to develop a reliable kick serve. The ProdigyMaker coaching blog, written by a former ITF pro futures competitor, calls the kick serve the hardest shot in tennis to learn, and describes players who struggle for years without correct instruction before finally mastering it. With proper coaching and a structured drill progression, players can see meaningful improvement within a few weeks, and a match-ready kick serve typically takes 4 to 6 months of consistent practice.
What Common Mistakes Happen With Kick Serves?
Common mistakes with kick serves include using the wrong grip, tossing the ball too low or too far in front of the body, swinging through the ball rather than brushing upward across it, losing balance and falling backward, and not using leg drive to push the body upward through contact. GoTennis coaching notes that a toss that is too low forces the racket to swing forward through the ball rather than up across it, which removes the topspin entirely. The fix for nearly every kick serve problem starts with the toss position and the upward swing path.
Where Should You Toss for a Kick Serve in Tennis?
For a kick serve, you should toss the ball slightly behind your head and toward your non-dominant shoulder, roughly at the 11 o’clock position above your body. For right-handed players, the toss goes over the left shoulder. For left-handed players, it goes over the right. According to UTR Sports’ kick serve coaching guide, a behind-and-left toss for right-handers encourages the vertical, upward brush swing path and safe contact needed to produce consistent topspin. The ball should also be allowed to drop lower than on other serves before contact, roughly 30 centimeters lower, so the racket can approach it at the correct sideways angle.
What Is the 25-Second Rule in Tennis and How Does It Affect the Kick Serve?
The 25-second rule in tennis refers to the time limit between the end of one point and the beginning of the next service motion. According to the ITF’s Rules of Tennis, players have 25 seconds between points once the balls are in play. A kick serve requires specific physical preparation: a deep knee bend, shoulder-over-shoulder coil, and a controlled toss. Taking your time within the 25-second window to compose your stance and visualize the toss position before starting your motion is entirely legal and strongly recommended. Rushing into a kick serve toss causes exactly the technical errors described above, and the additional bounce height the kick serve produces is worth nothing if the ball lands out or in the net.
Is a Kick Serve Harder on Your Shoulder Than Other Serves?
A kick serve places similar shoulder loads to a flat serve, but places additional stress on the lower back through the back arch needed to toss the ball behind the head. Research published in PMC found that the mean compressive force on the shoulder during the forward swing was approximately 220 Newtons for both flat and kick serves, with no significant difference between serve types at the shoulder joint. However, biomechanics research published in Tennisresor’s serve analysis guide notes that kick serves with the racket head further behind the body can increase both shoulder and back injury risk compared to flatter serves. Strong leg drive and a technically correct motion reduce this risk by distributing the load across the whole kinetic chain rather than concentrating it in the shoulder and lower back.
How Can Private Tennis Lessons Help Develop a Kick Serve Faster?
Private tennis lessons help develop a kick serve faster because a qualified coach can watch your grip, toss position, swing path, and leg drive in real time and give you immediate, specific feedback. The kick serve is too complex to reliably self-diagnose. Players who attempt to learn it without guidance often practice a motion that looks like a kick serve but produces little spin, and the wrong habit becomes deeply ingrained before they realize the problem. Private lessons at Hillcrest Tennis Camp are available seven days a week for both juniors and adults, led by coaches with international competitive and coaching backgrounds who understand exactly where the spin is being lost and how to fix it quickly.
Final Thoughts
The kick serve is the most difficult shot in tennis to develop, but it is also one of the most rewarding once it becomes reliable. A consistent kick serve transforms your second serve from a defensive ball your opponent attacks into a high, moving ball they are forced to neutralize before the rally even starts. The keys are the continental grip, the toss behind the head over the non-dominant shoulder, the steep upward brushing motion from 7 o’clock to 1 o’clock, strong leg drive pushing you upward through contact, and patience with the learning process. Use the fence brush drill and the knee-serve drill to build the motion before you ever hit full serves from the baseline. Be consistent with practice, twice a week for 20 to 30 focused minutes, and you will see results within weeks rather than years.
Players across North York, from the Willowdale area along Yonge Street and Sheppard to the Don Valley Village and Seneca Village corridors, are building their games at Hillcrest Tennis Camp because the coaching team brings elite-level experience to every session.
