Tennis Forehand Technique: How to Hit a Modern Forehand
Good tennis forehand technique means an early unit turn, a low-to-high swing path that brushes up the back of the ball, and a relaxed wrist that releases through contact into a full follow-through. Formfix checks all of this from a single iPhone video or photo and returns a 0–100 score with the #1 thing to fix in under 15 seconds.
The forehand is most players' biggest weapon — and the shot with the most variation in technique. This page covers what good form looks like, the mistakes that cost you consistency, and how to film your strokes for analysis.

Early unit turn
Shoulders and hips turn as one the moment you read the ball — the racket goes back with your torso, not just your arm.
Racket below the ball
At the start of the forward swing the racket head is below ball height, so the path up creates topspin.
Contact out in front
You strike the ball in front of your front hip, at roughly waist height, with your weight transferring forward.
Low-to-high brush
The racket accelerates up the back of the ball — the 'windshield wiper' — producing topspin that pulls the ball down.
Relaxed, loose arm
The arm stays loose through contact; tension kills racket-head speed. The whip comes from relaxation, not effort.
Full follow-through
The racket finishes over your opposite shoulder or by your hip (depending on style), with your chest rotated toward the net.
Most common mistakes and how to fix them
Late preparation
Why it happens: Turning only when the ball crosses the net leaves no time to set up, so every ball gets armed.
Fix it: Cue 'turn as soon as you read it.' Split-step as your opponent hits and start the unit turn before the ball bounces on your side.
Arming the ball
Why it happens: Swinging with just the arm — no hip or shoulder rotation — caps power and consistency.
Fix it: Cue 'hips first, arm last.' Shadow swings in slow motion, feeling the rotation start from the ground up, then rally at 70% speed.
Hitting too flat
Why it happens: A level swing path with no low-to-high brush sends balls long or into the net with no margin.
Fix it: Cue 'drop the racket below the ball, brush up.' Practice hitting with net clearance of 3–4 feet and let topspin bring it down.
Contact too close to the body
Why it happens: Getting jammed happens when you don't adjust your feet to the ball's position.
Fix it: Cue 'hit it out in front.' Keep adjusting with small steps until the ball is at a comfortable distance — film from the side to see your contact point.
No follow-through
Why it happens: Stopping the racket at contact decelerates before the ball leaves the strings — a consistency killer.
Fix it: Cue 'finish over your shoulder.' Exaggerate the follow-through in practice until it becomes part of the swing, not an add-on.
How to film it for analysis
Camera angle
Side-on (perpendicular to the baseline) at chest height shows the swing path, contact point, and follow-through. From behind shows spacing and rotation.
Distance
15–20 feet (4.5–6 m) away, framing from your feet to above your head at full follow-through.
Framing
Keep the phone still and film a rally or basket drill — 5+ forehands in a row shows whether your form holds up ball after ball.
FAQ
How do I get more topspin on my forehand?
Start the racket below the ball and accelerate up the back of it with a loose wrist — the low-to-high brush is what creates spin. A semi-western grip makes this easier; an eastern grip needs more forearm roll.
Where should I make contact on a forehand?
Out in front of your front hip, at roughly waist height, with your arm comfortably extended. If you're hitting beside or behind your body, your footwork is late — adjust earlier with small steps.
Why do my forehands fly long?
Usually a flat swing path with no topspin, or opening the racket face at contact. Add the low-to-high brush and check on video whether your racket face is vertical at contact.
What grip is best for a modern forehand?
Most modern players use an eastern or semi-western grip. Semi-western makes topspin easier and handles high balls well; eastern is more versatile for flat shots and low balls.
How do I film my forehand for a form check?
Side-on at chest height, 15–20 feet back, phone still, several strokes in frame. Upload to Formfix for a 0–100 score and the #1 fix in under 15 seconds.
