Kicking is all about practise to be honest. The more you kick, the more you will discover what works for you, and you can adapt that in order to make yourself a better kicker. I stay behind for a fair amount of time after training kicking (both out of hand and off the tee), and as I say, that is the greatest tip I can give you.
Anyway - this is what wors for me..
1. Placing the ball – the angle of the ball should be slightly tilted towards the target, though some kickers will prefer the ball to be more upright.
2. The landing area – the non-kicking foot must land on a firm piece of the turf (remember Beckham’s penalty). Try to make sure the surface is even and dry. This needs careful placement of the kicking tee. Stamping down the ground next to the tee can also help.
3. The targets – don’t aim for “between the posts”, try to pick a specific target in the background. The more you practise, the more, the better you get at hitting it; the more precise you get, the margin for error is reduced, and the easier it becomes.
4. The run-up – there is no exact science here because the shape, size and abilities of kickers are all so different. The run creates the momentum to kick.
5. The non-kicking foot – this should land next to the ball with the toe facing the target (or just outside).
6. The kicking foot – aim to hit the ball just below the middle, on one of the seams. Coaches talk about a hard foot – point the big toe to help create this feeling.
7. The hips – should be facing the target at the point of contact.
8. The eyes – from the start of the run up they have never left a specific point on the ball.
9. The follow-through – kick through the ball towards the target and let the leg follow-through on this line.
At least nine points to remember – but try to let your kickers focus on only one of them – probably the point of the ball is the most helpful. It keeps the head in.
As I say, it might not work for you, but I hope it helps..
