Here’s a putting drill that’s alot like a game of darts.
Cut out three circles from paper. The smallest one would approximate the size of a golf hole, the second about 2 to 3 times larger, and the third about 2 to 3 times larger than the second . Place these circles on the floor, creating targets, and assign points for each one.
The center circle is 10 points, the second circle is 5, while the outer most circle is 2. Take 10 putts and see what kind of score you get. Btw a score of 70 – 90 is excellent!
Compare your results with practice on artificial putting greens.
