Here is a terrific drill to time out your arm swing. You can coordinate it easily with the turn of your body back and through. In fact you will have to do it or the clubs will start to bang together. Do it with two golf clubs. Put them out in front of you about eight inches apart. As you take the clubs away we are trying to keep the clubs together, so you should practice going halfway back to halfway through. They should move at the same rate. It looks easy but it really is not. A lot of times people will be banging those clubs together right away or having one cross over the other. So you go halfway back to halfway through. Then as you get a little better at that you can go to the three-quarters position back to three-quarters position through. Then as you get better at that all the way back to the top, don’t bang them together, and then all the way through. Then you do that in speed. It is a terrific drill for getting the timing and feel of the golf swing. It will take a little bit of practice, but it will be well worth your time.
