After a bit of a purple patch last year, when I got my handicap down from 13 to 10, I have been slightly struggling with my game so far this year, only averaging about 30 points, and my handicap has gone back up to 11. I have just realised that my posture at address had got a bit poor. Bending more from the hips and sticking my backside out a bit more has transformed my ball striking. I had been hitting too many fat shots and even the occasional sh@nk. Also my back aches less after a round of golf. Result!
