friend is taking up tennis; he was inspired by Wimbledon Anyway, he's a little frustrated w/ his teaching pro regarding the serve. The pro wants him to learn serving w/ just the arm movement and then later add the waist and hip thrust. I tend to agree w/ the pro; my friend insists that he should be using all components of the serve to keep it together and smooth. I guess since my friend feels this way, he should go that road. I was just wondering for those that teach or have been taught, is it not easier to learn one component at a time?
