Set up 10 golf balls in a row beginning 1 foot from the cup and spaced 1 foot apart out to 10 feet. Find a spot 4-6 inches in front of the ball along the target line to align the putterface with. Set your stance so the big toe on your back foot is approximately 1 inch behind the back of the ball.
Look at the cup first then allow your eyes to follow the target line back to the spot 4-6 inches in front of the ball you chose. On the back stroke, stop when the putterface is flush with the big toe on your back foot. Roll the ball to the cup allowing the putter to finish high on the forward stroke.
Putt each ball to the cup remembering that the length of the back stroke determines the length of the putt. Use the scale, a 1 inch back stroke equals a1 foot putt.
Although spot putting is used to square the putterface with the cup during the stroke it promotes a smooth, consistent putt stroke. The tendency is to either push the putt if your back stroke is too short or pull the putt if your back stroke is too long. The goal of this drill is to synchronize the length of the back stroke with the tempo.
