Hey Eric, I noticed on your threads your a Certified Trainer? Is that fitness trainer? If you are here is my question. I am familiar with the static methods to build up the shoulders such as weights etc. I am looking for particular exercises that strenghten the shoulders a little more dynamically. Looking for more tennis specific stuff. I know of the weighted racquet and the "bungi" cord kind of training, do you know of some stuff that you really were impressed by the improvement in strength it gave your students fo tennis? Or is this pretty much it?
