Right now, my wife is still learning, so I go to the range often for her sake. I like to call it practice. My routine is to some sense have no routine. I try to simulate a "round" on the practice tee. I hit a drive...then pull a mid-iron...then maybe a wedge. I constantly hit different clubs from different lies. After we finish off our bucket we head over to the chipping area. I usually pull out a sleeve of my own balls and chip 3, putt 3, chip 3, putt 3. Then I might putt for awhile. There I do three major drills: long lag putts, putt some balls that circle the cup at the same distance, and work on speed by lining up a string of balls.
Thats it...I they had a good sand pit I would work on my sand game.
