Using an Impact Bag
A goal that all of you should try to achieve is a good strong solid impact position. That is how you hit solid straight golf shots. Now I have an impact bag here, you can also use a tire or fill a laundry bag with old cloths. As I set up I am actually going to position the contact point of the bag at my sternum.
Impact Position With a Short Iron
So with a short iron I will actually start with a little bit of weight against my front foot. Now as I go into my backswing and as I start into the ball the body starts driving into the front leg and at the same time I am releasing the club. What we notice is that the club starts at the bag and ends at the bag, the difference is the drive of the body and where the weight is distributed. With a short iron I have more weight on my front foot, which creates that descending or downward strike that you have all heard about and that is why good players take their divots after impact. Those of you hitting fat shots would tend to be too stagnant in the body.
Impact Position With a driver
Now to give you an example of a driver impact, I will position the contact point about two inches ahead of center, start with my weight balanced, and my body will make a little bigger wind-up in the backswing. As I move into my front leg and release the club I am not as much into my left leg and I am hitting the bag at a slightly more level to upward angle. A key element that you will notice is that the club is returning but the body is in a much more dynamic position. You can see that I am getting some drive from the center of the body timing with the golf club. As you can see from this demonstration, if you work with your impact position, and get into a better impact position you are going to hit stronger, straighter golf shots.
