When you go to the driving range before you play your round, you should work on your timing... not to fix your swing.
Make half length, half paced practice swings. It needs to be a slow movement back and through. It will work because you will feel the clubhead during the swing and you will naturally slow you down.
The aim is to keep the club shaft in front of you throughout the shot. Poor ball striking often stems from tension in the hands. When you have tension in your hands you lose mobility in your wrists and your feel of the club.
If you are losing shots to the right, blocking drives, your lower body might be releasing too quickly. This is a fault that causes the clubhead to get left behind as your body turns through. In this instance, you need to slow down your lower body release. Hit some practice shots with a wider stance. This will help your arms stay connected to the rotation of your body for much better strikes.

Most players understand the fundamentals of pitching and chipping. They know to set up in a slightly open stance and to favour the front foot. They know they should accelerate through impact and let the loft on the clubface provide the height and spin they need to stop the ball close.
Why do they still hit bad shots? Because they get caught up in trying to control the distance the ball goes without really knowing how to do it. They decelerate on short shots and swing wildly on the longer shots.
Vary your Backswing
It is very difficult to control distance by swinging faster or slower. Rather develop a system of wedge distances by varying how far you take back the club. Let’s say that in Picture 1 Brenden will with his Lob Wedge hit the ball 40 meters. His left arm angle points towards 8’o clock.
In Picture 2 Brenden’s left arm is parallel to the ground. He knows that when he stops his swing here he hits the ball 55 meters. In Picture 3 his left arm angle is towards 10 o’clock. He is able to hit the ball 75 meters when he stops his swing at this point.
By spending time on the range and practicing this system he will be able to better control his wedges. It is very important to control the speed of the swing, to accelerate through the shot and to keep in control of the swing. He will lower his score and ultimately enjoy his golf more.
