When you are searching for somewhere/somebody to do lessons, it is important to find somebody that will train individualized drills/mechanics. I believe that no two people are alike, therefore our bodies work differently and finding somebody that works 1 on 1 is essential! There are many programs that train very general drills that everybody does. While some of these are okay, not every player has the same issues! Find someone who knows how to train your specific body and personalize training to you!
