Mix it up
Just don’t hit you favorite club, try mixing what club you hit and try different shots. You may want to see what happens when you move the ball forward or back in you stance. Keep good notes as well. Writing down your results in a little journal or scrap piece of paper can be helpful the next time you are out on the course.

Work on alignment and distance
It is very easy at a range to just flail away at each shot as you usually have a large open area. However, make the most of your time by aiming at a flag or other focal point. You may also want to ask the operator at the range if the tees are up or back if the flags or signs have yardage markers associated with them. Pay close attention to the wind direction as well, just the same as you would have on the course. If you are hitting the ball more right than normal, it very well could be a strong cross-wind and not your swing.
