The key to effective practice is that it is not the quantity of training that leads to improvement but the quality. As a young boy, I quickly learned that chipping a bag of balls towards the same target on the practice green was of little use. By manipulating the task, for example, playing shots from different lies, different distances, and utilising different heights, plateaus in learning were breached and transfer of new skills to the course became easy.
Essentially the idea is to make practice harder so that improvements can be transferred to the course when it really matters. The following list of drills can be used to achieve similar results in other dimensions of the game.
"To improve, you must practice. But the quality of your practice is more important than the quantity”
DR BOB ROTELLA
1) Putting- put two tees either side of the hole so that you effectively make the hole smaller.
2) When playing a round select a tough driving hole. Take 3 brand new (expensive!) golf balls and going through your pre shot routine, hit 3 drives. I guarantee this will feel different to whacking them down the range.
3) Take two shots off the tee and play your worst ball.
Try adding these drills to your practice. At first they may be difficult but in the long run I am sure that they will help to improve your game.
