- Aggressive Baseline PlayIntermediateAggressive baseline play is a style built around taking the ball early, hitting with pace and depth from the baseline, and dictating rallies rather than waiting for opponent errors.
- Anticipation and Reaction TimeIntermediateAnticipation is reading cues from an opponent's preparation, body position, and court positioning before contact to start moving earlier, effectively buying more time than raw reaction speed alone provides.
- Approach ShotIntermediateAn approach shot is struck off a short ball as the player moves toward the net, designed to put the opponent under pressure. At the same time, allowing time to close into a volley position.
- Approach to NetIntermediateApproaching the net is the tactical decision to move forward from the baseline toward the net after an approach shot or serve, aiming to put away the point with a volley or overhead.
- Balance Through ContactIntermediateBalance through contact means the body's center of mass stays controlled and stable through the moment of impact, even. At the same time, moving. This allows the swing to transfer its full power and direction into the ball.
- Block ReturnIntermediateA block return uses almost no backswing at all, absorbing the serve's pace with a firm, stable racquet face to redirect the ball back deep.
- Body ServeIntermediateA body serve is aimed directly at the returner's torso or hip, denying them room to swing freely and forcing a cramped, defensive return.
- Challenge System (Line Calls)IntermediateThe challenge system lets a player dispute a line call using electronic ball-tracking review, with a limited number of unsuccessful challenges allowed per set.
- Chip ReturnIntermediateA chip return uses a short, compact slice motion to redirect a fast serve back low and controlled, prioritizing consistency over pace.
- Closed-Stance BackhandIntermediateA closed-stance backhand steps the front foot across toward the net before contact. This allows a full weight transfer forward into the shot at the cost of slightly slower recovery.
- Contact Point DriftIntermediateContact point drift describes an uneven contact location from swing to swing. This means sometimes in front, sometimes late, sometimes too close to the body. This means that produces hard to predict results even with a repeatable swing shape.
- Core Rotation in StrokesIntermediateCore rotation is the turning of the torso between the hips and shoulders during a stroke, transferring energy from leg drive and hip rotation up into the arm and racquet.
- Counter-Punching StyleIntermediateCounter-punching is a defensive-minded style that absorbs an opponent's pace, redirects it back with consistency and depth, and waits patiently for the opponent to make the error.
- Court PositioningIntermediateCourt positioning is where a player stands between shots, continuously adjusted to maximize coverage of the opponent's most likely replies while minimizing defensive vulnerability.
- Cross-Step RecoveryIntermediateCross-step recovery uses a crossover stride. This means one foot crossing in front of or behind the other. This means to cover ground quickly when returning to a base position after a wide shot.
- Crossover StepIntermediateThe crossover step is the explosive first step after the split step, where the foot on the side away from the ball crosses in front of the body to generate maximum lateral acceleration.
- Defensive SliceIntermediateA defensive slice uses underspin to keep the ball low and floating with minimal effort, letting an out-of-position player buy time and stay in the point rather than attempt a full topspin shot.
- Down-the-Line ShotIntermediateA down-the-line shot travels parallel to the nearest sideline, changing the direction of a crosscourt rally to create a sharper angle or exploit an open court.
- Drop ShotIntermediateA drop shot is a softly struck groundstroke or volley designed to land just over the net with minimal forward bounce, drawing the opponent in from the baseline and winning the point through touch.
- First Serve PercentageIntermediateFirst serve percentage is the share of first serves that land in the box, a core indicator of serve rhythm and risk management.
- Flat BackhandIntermediateA flat backhand is struck with minimal net racquet-face tilt and a swing path close to level through contact. This produces a low, penetrating trajectory with less topspin than a standard drive.
- Flat ServeIntermediateA flat serve is struck with minimal spin at maximum racquet-head speed. This produces the highest velocity and least margin for error of the three main serve types.
- Grip ChangeIntermediateA grip change is moving the hand along the handle between shots to match the incoming ball. The cause is often a forehand hold to continental for volleys, serves and slices.
- Grip Change Speed Between ShotsIntermediateGrip change speed is how quickly and reliably a player rotates the racquet in their hand between strokes that require different grips. A slow or incomplete change is a frequent hidden cause of mis-hits.
- Hip RotationIntermediateHip rotation in tennis is the turning of the pelvis from the coiled backswing position toward the target during the forward swing, the primary driver of power in the kinetic chain.
- Inside-Out ForehandIntermediateAn inside-out forehand is played by running around a ball that arrives on the backhand side and redirecting it with the forehand to the opponent's backhand corner.
- Kinetic ChainIntermediateThe kinetic chain in tennis is the sequential transfer of force from the ground up through the legs, hips, torso, shoulder, arm, and racquet, each segment accelerating the next to multiply racquet-head speed.
- Kinetic Chain BreakdownIntermediateA kinetic chain breakdown happens when the ground-up sequence of leg, hip, torso, and arm rotation is interrupted or skipped. This forces the arm to generate power on its own instead of receiving it from the body.
- Late Contact (Tennis)IntermediateLate contact means the racquet meets the ball behind the ideal contact point. This means usually behind the front hip. This means which robs the shot of pace, direction control, and spin.
- Late Split StepIntermediateA late split step lands after the opponent has already struck the ball, meaning the player is still airborne or resettling exactly when they need to be pushing off toward the shot.
- Leg Drive on GroundstrokesIntermediateLeg drive is the push off the ground during a groundstroke that initiates the kinetic chain, converting ground reaction force into upward and rotational energy that feeds into the hips, torso, and arm.
- LobIntermediateA lob is a high, arcing shot designed to clear a net player's reach, either buying time defensively or winning the point offensively with a topspin arc that lands near the baseline.
- Long Backswing Timing IssueIntermediateA long backswing timing issue occurs when the backswing takes longer to complete than the ball allows. This forces a rushed or unfinished forward swing regardless of how clean the backswing shape looks in isolation.
- Loop BackswingIntermediateA loop backswing takes the racquet back and up before dropping it down into the forward swing. This uses the circular path to build racquet-head speed and rhythm.
- Loss of Balance on Stretch ShotsIntermediateLoss of balance on stretch shots happens when a wide, low, or hard-hit ball forces a player to reach beyond a stable base. This causes the center of mass to fall away from the shot at contact.
- Moon BallIntermediateA moon ball is a very high, heavily topspun groundstroke hit well above net height to disrupt an opponent's rhythm and buy recovery time without going as high or defensive as a full lob.
- Movement PatternIntermediateA movement pattern is the sequence of footwork steps a player uses to reach the ball, execute the shot, and recover to position. This means combining split step, approach steps, stance, and recovery.
- Net Approach TimingIntermediateNet approach timing is when a player moves forward to the net relative to their own shot and the opponent's reply, aiming to split step just as the opponent makes contact.
- One-Handed BackhandIntermediateA one-handed backhand is struck with only the dominant hand on the grip, offering greater reach and disguise than a two-hander at the cost of stability against high-bouncing pace.
- Open StanceIntermediateAn open stance positions both feet roughly parallel to the baseline at contact. This allows the hips to rotate powerfully through the ball without requiring a weight transfer step.
- Open-Stance ForehandIntermediateAn open-stance forehand is hit with the front foot and hips facing the sideline rather than the net. This allows hip rotation to generate power without a full weight transfer forward.
- Overhead / SmashIntermediateThe overhead (or smash) is a serve-like stroke struck above the head to put away a lob, demanding quick shoulder turn, a trophy-position racquet path, and aggressive pronation through contact.
- Overhead Smash FootworkIntermediateOverhead smash footwork is the pattern of small adjustment steps and a final scissor or step-in motion that positions a player under a lob to hit it with full power and balance.
- Passing ShotIntermediateA passing shot is hit by the baseline player when the opponent has approached the net, aiming to place the ball past the net player through an angle or pace that cannot be volleyed.
- Poaching (Doubles)IntermediatePoaching is when the net player in doubles crosses over to intercept a return or rally ball meant for their partner, cutting off the angle and finishing the point at the net.
- Polyester StringIntermediatePolyester string is a stiff, low-elasticity monofilament string that provides superior spin potential and durability but transmits more shock to the arm compared to natural gut or multifilament strings.
- Racquet Face Angle at ContactIntermediateRacquet face angle at contact is the tilt of the string bed relative to vertical at the instant the ball is struck. It is the primary factor determining the ball's launch direction and spin type.
- Racquet Head SpeedIntermediateRacquet head speed is how fast the racquet head is traveling at the moment of contact. It is the single largest determinant of ball pace and spin on a given stroke.
- Rally ToleranceIntermediateRally tolerance is a player's ability and willingness to sustain longer point exchanges without forcing a low-percentage shot, reflected in average rally length and shot patience under pressure.
- Recovery StepIntermediateThe recovery step is the movement made immediately after hitting a shot to reposition at the optimal defensive or offensive base before the opponent's next ball.
- Recovery to Center CourtIntermediateRecovery to center court is the movement back toward a balanced base position after hitting a shot, positioned to cover the widest possible range of the opponent's likely replies.
- Return of Serve PositioningIntermediateReturn of serve positioning is where a returner stands before the serve. This means how far behind the baseline and how far side to side. This means set to counter the server's pace, spin, and typical patterns.
- Rushing the Split StepIntermediateRushing the split step means landing from the hop too early, before the opponent has actually struck the ball. This leaves the player flat-footed and unable to react to the true direction of the shot.
- Second ServeIntermediateThe second serve is the follow-up attempt after a fault. This requires enough spin and margin to give the serve a wide safety margin. At the same time, still limiting the returner's options.
- Second Serve SpinIntermediateSecond serve spin is the extra rotation a player adds to the follow-up delivery to raise net clearance and margin for error after a miss.
- Serve-Plus-One PatternIntermediateServe-plus-one is a tactical pattern where the server plans the first shot after the serve before the point starts. This uses the serve to set up a predictable, attackable ball.
- Short Backswing CompensationIntermediateShort backswing compensation is when a player shortens the backswing under time pressure to force contact, sacrificing racquet-head speed and stored energy to keep the swing "on time."
- Shot SelectionIntermediateShot selection is the real-time tactical decision of which shot type, direction, pace, and spin to use on each ball, based on court position, ball height, opponent location, and score situation.
- Slice ServeIntermediateA slice serve applies sidespin by brushing around the outside of the ball. This causes it to curve away from a right-handed server's deuce-side opponent and stay low after the bounce.
- String TensionIntermediateString tension is the tightness at which strings are pulled through the racquet frame, measured in pounds or kilograms, influencing the trampoline effect, control, and power of the string bed.
