- Short Backswing CompensationIntermediateShort backswing compensation means shortening the backswing under time pressure to force contact "on time," losing racquet-head speed and stored energy.
- Shot SelectionIntermediateShot selection is the real-time choice of shot type, direction, pace, and spin. It depends on court position, ball height, opponent location, and score.
- Shoulder Pain From ServingIntermediateShoulder pain from serving is often linked to overuse and to a serve driven by the arm instead of the legs and trunk. Common contributing factors include a toss behind the head, a sudden increase in serving volume, and weak or tight shoulder and upper-back muscles. Stop if it hurts, and see a qualified medical professional if the pain persists.
- Shoulder Prehab Exercises for TennisIntermediateShoulder prehab for tennis usually targets three areas. They are the rotator cuff muscles that turn the arm outward, the muscles that control the shoulder blade, and stiffness at the back of the serving shoulder. Common examples are band external rotations, rows and band pull-aparts, and gentle cross-body or sleeper stretches. Stop if anything hurts.
- Singles Patterns of PlayIntermediateA core singles pattern is to rally crosscourt until you get a shorter or weaker ball, then change direction down the line or attack. Others include the inside-out forehand to the opponent's backhand, the serve plus one and the approach down the line. Patterns give each shot a job.
- Slice ServeIntermediateA slice serve adds sidespin by brushing around the outside of the ball. From a right-hander, it curves away from the deuce-side returner and stays low.
- Sliding on ClayIntermediateTo slide on clay, start the slide a step or two before you reach the ball. That way you hit while sliding or just as you stop, not after. Lower your hips, spread your feet and bend your knees, with your weight on the sliding leg and that foot pointing where you are going. Stay balanced through the shot, then push off the sliding leg to recover.
- String PatternIntermediateString pattern is the number of main (vertical) and cross (horizontal) strings, such as 16x19 or 18x20. An open pattern like 16x19 lets the strings move more for extra spin, launch and power. A dense pattern like 18x20 gives a flatter, more controlled ball and usually lasts longer.
- String TensionIntermediateString tension is how tightly a racquet is strung, in pounds or kilograms. It shapes the string bed's trampoline effect, control, and power.
- T-ServeIntermediateA T-serve is aimed at the center service line. It uses the shortest path for speed and takes away the returner's easiest angles.
- Tennis Drop StepIntermediateA drop step is the first move back for a deep ball or a lob. Step back with the foot on the side of the ball and turn your hips and shoulders in the same move. Then shuffle or cross over into position, so you can hit from balance instead of backpedalling.
- Tennis Fitness and ConditioningIntermediateTennis fitness is about repeated short sprints with quick recovery, not long steady runs. Train with intervals that mimic points, agility and footwork drills, leg and core strength, and an aerobic base for long matches. Build it up gradually alongside your tennis, and keep at least one easy day between hard sessions.
- Time ViolationIntermediateA time violation is a penalty for taking too long between points or at a changeover. Under USTA rules the first one is a warning and each one after that costs a point. Pro tours set their own shot-clock penalties.
- Top of the Bounce (Choosing Contact Height)IntermediateHitting at the top of the bounce is a good default for an attacking groundstroke. The ball is at a comfortable height and is moving slowest up and down. Take it on the rise when you need to steal time. Let it drop when you are pushed back and need more time.
- Trophy PositionIntermediateThe trophy position is the serve checkpoint at the toss's peak: hitting arm up, body arched, tossing arm raised. The kinetic chain is fully loaded to fire.
- Two-Back Formation (Doubles)IntermediateBoth players stay back in doubles when the other team controls the net: against a dominant net player. A strong serve-and-volley team, or when your own volleys are weak. It is a defensive formation that buys time to reach hard volleys and cover lobs. From two back, hit low balls between the net players, lob over them, and move forward together as soon as you get a short ball.
- Two-Up Formation (Doubles)IntermediateTwo up, with both partners at the net, is usually the strongest position in doubles. This is because volleys are easier to put away from there and the other team has less time. Move forward together on a short ball, stand around the middle of your service boxes slightly staggered, and cover the middle first. The main risk is the lob, so do not crowd the net.
- Unit TurnIntermediateA unit turn is rotating the hips and shoulders together as one unit to prepare for a groundstroke. The arm does not take the racquet back on its own.
- Volley TechniqueIntermediateVolley technique is the mechanics of striking the ball before it bounces. It uses a short, firm punch action rather than a full groundstroke swing.
- Walkover, Retirement and DefaultIntermediateA walkover means a player never starts the match, usually because of injury, illness or a personal reason, so the opponent goes through without playing. A retirement means the match started but a player could not finish it. A default is different: an official removes the player, for example for not showing up or under the point penalty system.
- Wide Serve (Deuce/Ad Court)IntermediateA wide serve is placed near the sideline of the service box. It pulls the returner off the court and opens the opposite side for the next shot.
- Wrist Pain in TennisIntermediateWrist pain in tennis is often linked to overuse, extreme grips, off-center hits and a tight grip. Pain on the little-finger side is commonly linked to western and semi-western forehands. The non-dominant wrist can hurt on two-handed backhands. Stop if it hurts, and see a qualified medical professional if the pain persists.
- Wrist Snap on ServeIntermediateWrist snap (pronation) on the serve is the forearm-rotation motion through contact that accelerates the racquet head and directs spin, the final link in the serving kinetic chain.
- Wrong-FootingIntermediateWrong-footing means hitting the ball back to where your opponent just came from, behind them as they recover. They are moving one way and must stop and change direction. Even a slow ball can win the point this way.
