I find timing comes more naturally when I'm not trying to hit the cover off the ball. Soon as I try to force things and hit the ball
hard, everything goes to pot!
This is what the last coach I had told me, and I find it has helped me a lot:
Relax each time you go to bat, and try not to think about what shots you are going to play. Take a few balls just to feel bat on ball and get your eye in. Then start to play your shots but not at full force. Soon as you get the confidence from timing and middling a few, you naturally start hitting the ball harder without thinking about it, but with the same timing and movement as when you were taking it easy.
Dunno whether it sounds a load of hokum or not, and I don't mind if the coaches on here shoot it down, but I find it has helped me
