Controlling Distance within 100 Yards
In golf, it's much easier to hit it with a full swing than to hit it with a half swing to adjust for distance.
For instance, if you hit your sand wedge 90 yards with a full swing, 60 yard shot is much harder to control.
Vijay Singh is known for practicing more than anybody else on tour. He uses the drill below to control distance within 100 yards.
1) Pick a distance that you can't use a full swing with a sand wedge
2) After hitting a shot, try to guess if you hit it short or too far without seeing the ball
If you can, you should guess which direction the ball went at the same time as well.
