When I used to take it serious every range session meant something.
I used to have my wee note book with me.
Whether it was getting all my distances down for 1/2, 3/4, punched, full out shots, or working a draw or a fade.
Or going only with the 4 wedges and getting my eye in.
At times I was playing all over so you get to know the courses you played so I used to mock play courses, Tee Off then play next from where you thought it would be from, everything but putting. Actually something Tiger does on the range.
Sometimes just working on a specific shot that cost me shots in previous medal or event.
Also think about the elements, use them as a challenge, work with and against the wind, practice punching under the wind and getting used to how much the rain pushes the ball down etc to getting use to clubbing in those conditions.
