How to smash harder

To smash harder in badminton, stop trying to hit hard with your arm. Smash power comes from a kinetic chain: legs push, hips turn, the trunk uncoils, then the shoulder rotates, the elbow extends and the forearm pronates, each link faster than the last, finishing with a relaxed grip that squeezes at contact. Get the order right and meet the shuttle high and in front, and your smash gets faster without feeling harder.

That's not folk wisdom. Biomechanics studies of the smash consistently name shoulder internal rotation, elbow extension and forearm pronation as the main sources of racket-head speed, fed by the legs and trunk in a proximal-to-distal sequence. Below: an interactive kinetic chain you can click through, nine fixes that add speed, drills to groove them, and a checklist that remembers your progress.

Badminton smash technique: the kinetic chain

Think of a whip. The handle moves first and slowly; each section after it moves later and faster, until the tip cracks. In a good smash the big, slow body parts start the movement and hand their speed on to smaller, faster ones. Research on smash mechanics finds the same pattern: the fastest rotations happen later in the swing and over a shorter time. Click each link of the chain for cues and the most common fault.

Skill, not size, drives most of the difference. In a study of 77 players at six levels, Phomsoupha and Laffaye (2014) found smash speed rose steadily with skill, with elite players hitting the shuttle about 138% faster than people who had never played. The players in that study were of similar height and weight across groups; what changed was technique.

How to smash in badminton, step by step

1. Move behind the shuttle. Get there early, so you can hit it in front of you, not above or behind your head.
2. Turn sideways. Racket-side foot back, chest to the sideline, non-racket arm pointing up at the shuttle.
3. Load. Weight on the back leg, racket up, elbow at roughly shoulder height, grip relaxed.
4. Drive and rotate. Push off the back leg; hips turn toward the net, then the chest.
5. Throw the racket. Elbow leads, the upper arm rotates inward, the forearm pronates, fingers squeeze at contact.
6. Hit high and in front. Racket face angled down, slightly bent arm, shuttle in front of the hitting shoulder.
7. Follow through and recover. Racket finishes across your body; step forward ready for the block or the net reply.

How to smash harder: 9 fixes that add speed

Most club players lose speed in the same places. Work through these in order; the early ones unlock the later ones.

1. Get behind the shuttle

You can't use your legs or trunk if you are reaching back for the shuttle. Late footwork is the number one smash killer. Our footwork drills you can do at home train the move to the rear corners.

2. Turn sideways and use your free arm

Standing square to the net leaves no room to rotate. Pointing the non-racket arm at the shuttle turns your chest for you, helps you judge the contact point, and pulling it down as you swing speeds up the trunk rotation.

3. Use your legs

Load the back leg and push. As you hit, the legs switch in a scissor kick: back leg comes through, front leg goes back. A jump smash adds height and angle, but only if you are balanced first.

4. Rotate hips before shoulders

If your hips and shoulders turn together, you lose the stretch across the trunk that stores energy. Shadow the movement slowly: hips, then chest, then arm.

5. Lead with the elbow and rotate the shoulder

The smash is a throwing action. Elbow up, then the elbow moves forward and the upper arm rotates inward fast. If you can throw a ball overarm, you already know this motion; a panhandle push of the racket skips it.

6. Pronate the forearm instead of flicking the wrist

"Use your wrist" is the most misunderstood cue in badminton. The snap at the end comes mostly from forearm pronation (turning the palm outward, like turning a door handle), not from bending the wrist. Pronation needs a proper forehand grip; see our badminton grip guide.

7. Relax the grip, then squeeze

A tight grip makes the arm stiff and slow. Hold the racket loosely through the preparation so the racket head can lag behind, then squeeze the fingers at contact. Many players find this alone gives a cleaner, louder smash.

8. Hit high and in front, without over-reaching

Contact in front gives you angle; contact behind your head sends the shuttle flat or into the net. But reaching up with a locked-straight arm isn't the answer either. In a study of elite Malaysian players (Ramasamy et al., 2021, Sports Biomechanics), whose fastest jump smashes averaged about 95 m/s, faster smashes were linked to not over-extending the elbow or over-raising the upper arm at contact.

9. Check your racket and strings

Equipment won't fix technique, but it can fight it. A racket that is too heavy or too head-heavy for you slows the swing and arrives late; a very stiff shaft rewards fast, well-timed swings but feels dead to slower ones. Strings strung tighter than your swing can handle shrink the sweet spot. The racket finder and string tension calculator suggest a starting point, and our guide on how to choose a badminton racket explains why.

How to smash powerful in badminton: drills

Speed comes from repetition of the right movement. These four drills cover the chain from the ground up.

• Overhead throws. Throw shuttles (or a light ball) overarm as far as you can, sideways stance, elbow leading. 3 sets of 10. This grooves the shoulder rotation and pronation without a racket to muscle.
• Shadow smash with a pause. Move to the rear corner, pause in the loaded position for one second, then swing. The pause exposes whether you are really sideways and on the back leg. 3 sets of 8 each corner.
• Fed smashes at 70%. A partner lifts to mid-court; smash at 70% effort with a loose grip, aiming at a target near the sideline. Clean contact first, then build to full speed. 20 to 30 shuttles.
• Smash, recover, kill. Smash, step in, and kill or net the block. Real rallies don't end with the smash, and recovery is part of smashing well.

Speed vs angle: what actually wins points

A faster smash isn't automatically a better one. Shuttles lose speed quickly to drag, so the receiver sees a much slower shuttle than the one leaving your racket. A steep smash from mid-court, or one aimed at the hip of the racket arm, often beats a faster smash from the back line. Mix in drops from the same preparation (see every badminton shot, explained) and your opponent can't sit back waiting for it.

Curious how you compare? Typical ranges are in how fast is a normal smash, and the records are in the fastest badminton smashes ever recorded.
