When I practice putting at home, I usually practice just my stroke. I don’t try to hit the ball at a target. I save that for the practice green at the range.
I’ll putt to a backstop about six feet away, trying to emulate this stroke, because there is so much that is good about it. See it at 0:30.
I concentrate on two things:
1. A gentle swing of the club back and through, keeping the clubhead low going back and going through, swinging the entire club, not just the clubhead. A putt, too, is a swing, not a hit.
2. Contacting the ball on the sweet spot, which I tell by sound. I want to make the right sound every time.
