Every golfer reaches that point where he feels he's mastered his technique. The form, the stroke, and the follow-through - everything is immaculate. And yet, you find that despite the poetry of your technique, the sheer beauty of perfection, you can't get the ball to fly any farther. You've bought all the clubs, you've read all the books, and you've pretty much gotten adjusting for the wind down pat.
If you can't think of anything left that can improve your game, maybe the problem doesn't lie in your technique, equipment, and expert knowledge of wind physics. Maybe you aren't getting the distance you want simply because you lack the physical power to do so.
Any sport that has physical activity, even golf, will require a bit of exercise to ensure a better game. Improving your drive can be as simple as working out. If you're serious about your long game, you'll find that muscle building for golf is one of the best things you can do.
It's common sense that the stronger your muscles are, the more powerful you'll be in activities that use those muscles. With this logic, we can see that strengthening the muscles you use in your swing will increase the power of your swing. The added force you put into your swing will find its way down the club and crash into the ball, sending it soaring farther than it normally would. However, simple strength training isn't going to be enough. You've got to develop your muscles according to how they're used in your swing. You've also got to consider the flexibility of your muscles. Too much working out will cause your muscles to enlarge, possibly limiting your flexibility. As a result, your form might be compromised. Your swing will have to adjust to the bulkiness of your body, and more often than not, it will compromise its quality.
The key, then, is to not merely work your muscles out, but to exercise and develop lean muscle. You've got to strengthen your muscles without bulking them up. Not only that, but you've got to develop the specific muscles you use in your swing. While all this may sound complicated, the answer to your strength training problems is quite simple: if you want to exercise your swing, exercise by swinging!
Here's how you do it: find a dumbbell. Make sure you're comfortable working with its weight. It should be heavy enough to provide resistance to your body motion, but not severely hamper it. When you've got a dumbbell you're comfortable with, hold it as you would a golf club, and start swinging! Because you're working with the weight in the same motions as your golf swing, the muscles involved in your swing are all getting worked out. Alternatively, you can also find and purchase a weighted golf club for the same purposes. Keep doing this on a regular basis, and your muscles will start to strengthen. In a month or two of disciplined exercise, you'll notice an increase in the distance of your swing. Keep the principles of this exercise in mind, and you can get more creative with your exercises.
