How to Practice Like a Tour Player John Elliott, GOLF Magazine Top 100 Teacher
You go through a bucket of range balls like a wave of locusts through a cornfield.
When you beat balls at a machine-gun pace you're not helping your game much. You need to set up to the ball correctly every time, and also take the time to follow through completely, study your ball flight and landing patterns, and then decompress and get ready for the next shot. In other words, you need to practice like you play.
How to do it
Watch Tour players on the driving range. Most pros follow a six-step procedure that takes them from ball to ball in a deliberate, measured way that mimics how they approach each shot on the golf course. If you mimic that procedure, you're guaranteed to become a better ball striker.
