Hi Dave Cahill here with Cahill Golf Schools in Minnesota at the Loggers Trail golf Course Learning Center. Today I am going to talk about address and your spine. There are a few misconceptions out there that it is necessary to have your spine absolutely straight. You can actually be relaxed and have the upper part of your back slightly rounded. If you take a look at almost every tour player you will notice at impact that their spine is rounded. Relax at address do not flatten out that upper spine. The upper thorax is slightly rounded. During a golf shot it looks like this.
