I am a female high school player. I had a tournament today and was playing 2nd Singles. My coach says that my shots are soft. What does it meant by soft? Does it mean that my shots are slow and weak? What type of strength(from wrist? Arm? or what?) should I use more to make my shots stronger? There's a period when my services went straight towards the baseline. My coach wanted me to try to serve more of that kind of service. However, I couldn't get it right all the time. How should I hit the shuttle to make the shuttle fly straight through? How do I position myself and the shuttle? I wanted to learn slicing the shuttle too. Will thaty make my shots stronger? I would be glad to know!
