I tend to lose my swing at the driving range, but recently I lost it the day before a round (I don't play too often). Sure enough, I still had trouble the next day. I went along with it and managed to get a few decent shots, but mostly poor ones. I shot over 110, a 112 or 113 I think. I've since played well finally playing a round at +18, an 85 on a par 67. All I want is to go back and tackle that course again.
Now at the drivin range, I get really technical and take my time trying to figure out what's wrong. You need to be critical and really patient, but I've managed to figure out my problems. Once I even fixed an emerging case of the $#@nk$ within an hour. It feels so good to figure out the problem when there is one. Almost as good as not having a problem. Almost.
I find that if I am thinking too much about the mechanics my swing tends to get worse. I find it easier to think about what I am trying to acheive, hit the fairway, hit the green, etc..... golf after all is a target game.
I usually know what I'm doing wrong, but when I have no clue I concentrate on keeping my spine angle and head still , then I try to hit the @*&$# out of the ball. I use my anger to intensify my focus on the ball.... at least that's what I tell myself. lol It usually works for me, though I wouldn't recommend it, except for the spine angle & head part... ;0)
you hit too many balls that day, 18 holes, and a range session, if your body wasnt just tired your mind was man, i'd lay off golf for a day or two, then get back in the game, sometimes when you get on the range you make a bad swing with a good result, and you repeat that and you get bad results, just mental i'd say, and as far as the guy behind you, just pretend he isnt there
I find that hurling a 9 iron in the direction of my last topped shot has a theraputic effect on my game.. If I accompany this action with a litany of all the four letter words I have learned since I took up this ghastly game, it seems to help even more. Beyond that, I try to calm myself before I have to take the next shot from behind whatever hazard I have managed to get the ball behind and make a good solid swing...
I have to be honest and tell you that NONE of these things are very effective, but they do relieve stress temporarily and my game eventually comes back of its own accord and on its own schedule.
I heard (don't know if it's true) that Nicklaus once said something like: "On 80% of bad shots, there was a problem at address." Anyway, if things are going inexplicably bad for me, I start making a conscious effort to check my set-up at address: grip, arms, spine angle, feet, ball position. That can fix an error in mechanics that may have crept in.
Another thing I'll do is to start using a favorite club, even if it won't get me to the green. Just something that I know I'll hit a good shot with. A few good shots and my confidence comes back.
