Most tennis players repeat the same technique errors for years without realizing it. AI form analysis identifies these mistakes frame by frame, giving you the specific corrections that actually improve your game.
1. Late Racket Preparation The most common error at every level. If your racket isn't back before the ball crosses the net, you'll always be late. Prepare your racket as soon as you see the ball direction — not when it reaches you.
2. Hitting With a Death Grip Gripping the racket too tightly (tension above 5/10) reduces racket head speed and causes arm injuries. Relax your grip to 3–4/10 during the swing, tightening only at contact.
3. Serving Into the Net Usually caused by tossing the ball too far behind you, causing you to hit down into the net. The toss should be slightly in front and to the right (right-handers), allowing you to hit up and through the ball.
4. Not Recovering After Shots Hitting a great shot and then watching it instead of recovering to the center of the baseline is one of the most common tactical errors. Always recover after every shot.
5. Arm-Only Groundstrokes Using only the arm (no shoulder rotation, no leg drive) produces weak, inconsistent groundstrokes. Power in tennis comes from the kinetic chain — legs → hips → shoulders → arm → racket.
