Hey Mason. I just looked at your badminton smash footwork. Your forehand side rearcourt footwork is wrong. Look at 2:12, if you pause the video when you start the movement you should notice that you are looking sideways. Try to have a sideways stance, but always look forward. If you then pause at around 2:14 right before you jump, notice how you are almost turned almost entirely away from the net. Again you should be facing forward but with a sideways stance, if that makes sense. Keep up the good work.
