One of the most common errors on the serve is not following through all the way to the non-dominant shoulder. Many players stop the paddle shortly after contact when the paddle is in front of their chest, or maybe even sooner in the swing. You may be thinking: “How does what I do after I contact the ball have anything to do with my shot?” But how you intend to follow through affects what your paddle does before contact. For you to stop the paddle shortly after contact means that you will decelerate before you hit, which is not optimal. The follow-through is a very important part of the swing on the serve.
Here’s a trick that will help you make sure that you remember the follow through every time:
At the end of the swing, catch the paddle with your non-dominant hand. You should finish the swing above your non-dominant shoulder with both hands on the paddle. It’s not possible to catch the paddle with your non-dominant hand without finishing at your shoulder!
