Actually, the power you use to hit the ball should not be as large as you can. Conversely, you will find many thin players that hit the ball very far. The reason for this is that they have learned to use leverage. The angle that is created between the club and your left hand is what you need to look at.
Never force yourself to hold this angle seldom works and results in a poor golf swing. You can hold this angle as long as possible, but not force. A more automatic way to hold this angle as long as possible is to think of the golf club as a whip and feel yourself whipping the cheap golf clubs as you swing.
Also, you can begin your downswing with a shift with your hip towards the target. This helps to store more energy in the Titleist AP2 716 Irons so that it is released at the last moment just before impact. This golf set is not as the same as the Titleist CB 716 Irons Australia.
Most people focus on swinging as hard as possible and using as much energy as they can. In fact the opposite tends to work the best when they try to hit their drives far. If you really want to hit the ball far you are better off focusing on swinging freely and under control. If you are always losing balance then this is a sign that maybe you are trying too hard so you need to back off a little.
By swinging the club comfortably you will also increase the chances of making good contact and launching the ball with the right kind of spin and trajectory which will help you much more when it comes to hitting it far and straight. Focus on accuracy and you will find that in time the distance will naturally follow.
Finally, you must trust your swing otherwise you will never develop real consistency in your golf game. Even if you hit your last drive out of bounds or in the lake you must believe that the next drive will go straight and far right down the middle of the fairway.Trusting your swing will allow you make better golf swings. Because golf is also a mental sport in many aspects. Everyone need a process to play gold well.
