Here is a tip for you seniors, or anyone who has a bad back for that matter. It scares me to death when someone comes for a lesson and when talking with them they tell me that they have some back problems that it kind of hurts them and then all of a sudden I see a golf swing that where the feet are planted and not moving. When I see a golf swing that looks like that what that individual is really doing without realizing it is putting a lot of torque on their back. When they do this and the harder they swing the more torque they put on their back as long as they have that right foot on the ground. So the first thing that I am going to do when I am teaching someone that has a back problem is I am going to try to get them up on that back foot and back toe as quickly as I possibly can. Something that looks like this. The quicker I can get them up on that back toe the less torque it takes on the back, the less problems they are going to have. So if you have back problems I highly suggest or recommend that you get on that back toe as quickly as possible. The more you swing keeping that back foot flat on the ground the more problems you are going to have with your back.
