How to get a good tennis swing: the six fundamentals every stroke shares
Disclosure: we make ShadowSwing, a swing trainer app mentioned on this page. It helps with one of the six fundamentals, and its section says which one and what it can't do.
Short answer: A good tennis swing comes from six fundamentals that every stroke shares: a balanced ready position, an early unit turn of shoulders and hips, contact in front of the body at a comfortable distance, a relaxed arm that lets the body lead, a racket path through the ball toward the target, and a full, balanced finish. Fix them one at a time, starting with contact.
Your forehand, backhand, serve, volley and slice are the same swing in different shapes. This page covers what they share and helps you find the part that's breaking down. Then it points you to the right stroke guide. New to the game? Start with tennis rules for beginners, then come back.
What a "good" tennis swing actually means
A good swing is one you can repeat. One huge forehand proves little; the same clean forehand twenty times in a row wins rallies. That's why many coaches put control first and speed second.
Coach Nick Saviano lists five characteristics of great technique on TennisOne: "simple, efficient, effective, flexible, and compatible with your personality." He also writes that "no standard technique or swing path for a stroke exists that is optimum for all players."
So treat every angle and position below as a coaching cue. Good players look different; they share the fundamentals.
The six fundamentals
1. Balance and a ready base
What it is: a stable, athletic stance (feet wider than the shoulders, knees bent, weight on the balls of the feet) and a split step as your opponent hits.
Why it matters: Saviano calls poor balance "one of the single biggest causes of errors in tennis." If your base moves while you swing, the racket moves with it.
No-ball check: hold your finish for two seconds. If you have to step to stay up, your balance broke earlier in the swing.
In each stroke: set base on the forehand and backhand, balanced landing on the serve, weight forward on the volley, low and sideways on the slice.
2. Turn early, as a unit
What it is: your shoulders and hips turn together and take the racket back with them, instead of the arm pulling it back on its own.
Why it matters: the turn stores energy and buys time. The USTA puts it simply: "think unit turn rather than simply racquet back." Coach David Kass, interviewed by adidas, describes the hips, torso and arms turning "as one unit."
No-ball check: a common cue is that at the end of your turn, your chin sits close to your front shoulder.
In each stroke: groundstrokes turn as you read the ball (how to hit a forehand), the serve turns through the sideways stance and trophy position (how to serve), and on volleys many coaches teach only a small turn.
3. Spacing and contact in front
What it is: meeting the ball in front of your body at a comfortable distance, not beside you or jammed.
Why it matters: the LTA tells beginners to "play the shot with the ball in front of your body." Tennis Method says the contact point exposes "footwork, timing, balance, swing path, and decision-making."
No-ball check: swing to a fixed spot in front of your front hip and freeze at contact for two seconds. Check the space between racket and body.
In each stroke: front hip on the forehand, further forward on the backhand, full reach on the serve and overhead smash, out in front on the volley.
4. A relaxed arm, with the body leading
What it is: power from the ground up, through the legs, hips and trunk, passed to the racket by a loose arm.
Why it matters: biomechanics research calls this sequence the kinetic chain, with leg drive and trunk rotation feeding the arm and racket (Elliott, Br J Sports Med, 2006). A tight arm is usually a slow arm. On TennisOne, King writes that "tension is designed to restrict movement," so "a tight forceful swing is usually not a fast swing."
No-ball check: grip at about three out of ten pressure, the cue used in the forehand and serve guides, and feel the racket head trail your hand and then catch up.
In each stroke: loose grip on groundstrokes, loose arm so the racket drops on the serve. The volley is the exception: many coaches teach a firm wrist and a short swing.
Go deeper: the drills, the mechanics and how to measure head speed are in how to increase racket-head speed in tennis.
5. Swing path through the ball
What it is: the direction the racket travels through contact. The path decides what the ball does.
Why it matters: Saviano notes on TennisOne that the face is very close to vertical at contact on most groundstrokes (the slice is the exception: he describes the face as only slightly open at impact), and that spin "has more to do with the path the racquet takes" than with the face. Low to high gives topspin; high to low, then forward, gives slice. Keep the racket moving toward the target through the ball.
No-ball check: swing along a straight line on the floor and watch the racket travel toward the target through the contact zone.
In each stroke: low to high on the forehand and backhand, up and out to the ball on the serve, short and forward on the volley, high to low and forward on the slice (how to hit a slice).
6. A full finish and recovery
What it is: letting the swing end naturally, then getting back to the ready position.
Why it matters: Saviano calls the follow-through "a great gauge" of the swing path, and he warns against trying to stop or slow it down. Stopping the follow-through also appears on T7FIT's list of common swing mistakes.
No-ball check: the same as fundamental 1. Hold the finish for two seconds, then split step.
In each stroke: over the opposite shoulder on the forehand, high over the shoulder on the backhand, down past the opposite hip on the serve, short stop on the volley, out in front toward the target on the slice.
The fundamentals in each stroke
| Fundamental | Forehand | Backhand | Serve | Volley | Slice |
|---|---|---|---|---|---|
| 1. Balance | Split step, then a set base | Set base, head still | Stable stance, balanced landing | Wide base, weight forward | Stay low and sideways |
| 2. Turn | Shoulders and hips turn together | Shoulders turn, racket goes with them | Sideways stance, then trophy position | Small turn, racket stays in front | Turn, racket back high |
| 3. Contact | In front of the front hip | Further in front, more so one-handed | Full reach, slightly in front | In front, short punch | In front, face slightly open |
| 4. Relaxed arm | Loose grip, racket head trails | Arms relaxed, slightly bent | Loose arm, racket drops | Firm wrist, no big swing | Smooth, arm straightens toward contact |
| 5. Path | Low to high | Low to high | Up and out to the ball | Short and forward | High to low, then forward |
| 6. Finish | Over the opposite shoulder | High, over the shoulder | Down past the opposite hip | Short, then stop | Out in front, toward the target |

What's wrong with my swing?
Match what you see to the cause coaches commonly point to, then go to the stroke guide.
| What happens | Common cause, as many coaches see it | Start with |
|---|---|---|
| The ball goes into the net | Late contact, or a path that's too flat or going down | #3, then #5 |
| The ball flies long | Face open at contact, or no low to high path | #5 |
| No power, you feel like you're pushing the ball | The arm swings alone, or the grip is tight | #2, then #4 |
| Your arm, elbow or shoulder is sore after playing | The arm is doing the body's job | #4, and see a doctor or physio if it keeps coming back |
| You feel jammed, or you're reaching | Spacing and footwork | #1, then #3 |
| Good one day, bad the next | No repeatable finish or check | #6, then the practice section below |
How to improve your swing: one fundamental at a time
Change one thing at a time. Work on three at once and you won't know which change helped. Many coaches suggest staying with one fundamental until it holds up in a rally.
A progression along the lines Tennis Method and ParentEdge describe:
- No ball. Do that fundamental's no-ball check, slowly, then at full speed. The full drills are in shadow swing drills for every stroke.
- Drop feed. Drop a ball and hit it with the same shape. If contact breaks on a self-drop, Tennis Method notes, it will break in a rally.
- Rally. Keep the same focus in a slow rally, then a normal one.
Film yourself now and then. Saviano Tennis suggests filming your swing every couple of weeks next to a model and fixing one difference at a time (Saviano Tennis).

Where ShadowSwing fits
ShadowSwing turns your phone into a swing trainer. You hold the phone like a racket handle and swing; the ball sound plays only when the racket head gets fast enough, so a pushed, tight swing stays silent.
It helps with one fundamental: #4, a relaxed arm and racket-head speed. It doesn't track your body, the ball or spin, so it can't check your balance, your turn or your contact point. Its 3D replay shows the racket head's path and where the face pointed, but it doesn't know where the ball was. Use a mirror or your phone camera for the rest.
It runs on iPhone (iOS 17 or later) and Android (8.0 or later), free to download, with no account. Pro removes the limits. On the US App Store, Pro is $4.99 a month or $39.99 a year. Prices vary by region.
Questions
How do you get a good tennis swing?
Build it on six fundamentals: stay balanced, turn your shoulders and hips early, make contact in front, keep your arm relaxed so your body supplies the power, swing through the ball toward the target, and finish fully. Work on one at a time, starting with contact.
What is the most important part of a tennis swing?
Many coaches would say the contact point. Where and when the racket meets the ball decides direction, depth and spin, and a late or jammed contact usually means the preparation or footwork went wrong first. Fixing contact gives the rest of the swing something to aim at.
Why does my tennis swing feel weak?
Usually because the arm is doing the work. Power comes from the legs and the rotation of the hips and trunk, passed through a relaxed arm to the racket. A tight grip and an arm-only swing tend to slow the racket head. Turn earlier and loosen your grip.
Is the tennis swing the same for every stroke?
The fundamentals are the same; the shape changes. Every stroke needs balance, an early turn, contact in front, a relaxed arm and a full finish. The path differs: low to high for topspin drives, high to low and forward for slice, up to the ball on the serve, very short on volleys.
How can I practice my tennis swing at home?
Swing with no ball, freezing at the end of the turn, at contact and at the finish, then repeat at full speed. A mirror or phone video shows your positions. Pick one fundamental per session, and pair it with court time, since no ball means no reading. See tennis practice at home.
How long does it take to improve a tennis swing?
It depends on how often you practice and how big the change is. Many coaches say a small change, like an earlier turn, can start to feel natural after a few weeks of regular work; rebuilding a stroke takes longer. Change one thing at a time, check it on video, and see a coach if progress stalls.
Can an app fix my tennis swing?
Not on its own. Camera apps can show your body positions from a video. Swing trainer apps like ShadowSwing, the app this site makes, respond to racket-head speed but don't track your body, the ball or spin. Use them alongside a coach or video. See do you need a camera to practice your swing at home?
