What are some badminton techniques that will improve my playing?

move your wrist not your arm. try bouncing the bird a few times out in front of you so you know how far a distance your racket goes. for hitting over head try throwing it up in the air and swatting it like a fly and imagine there is a net about fifteen feet in front of you , change the distances once you get the hang of it, so you know the angles you are supposed to hit it, hit it with different strength and so you see how far you can hit and how far you should hit it. try to stay in the middle of the court so you dont have to run to the opposite side if your playing one on one because chances are your not gonna get to it in time. throw the bird out in front of you to where its a bit out of reach so you have to bend your knees and go under it before it falls. you get a few of those and those are the ones that are hard to get so having that down will help save you a few times.
