As the title says, I'm trying to help my friend become a better badminton player...I am not a coach, so my advice is limited and he doesn't really get my explanations coz I'm an intuitive learner...Question 1. Why do people stand so close to the service line in singles when it's easier to stand further back to cover long serves and it's easier to move forwards than backwards to get short serves... Question 2. Every time I smash or clear I hit my knee when I cross the racket across my body...why is that? Question 3. When I smash or clear, should I be hitting the bird square on my racket or should my racket be angled a certain way...(he hits all his smashes and clears like flat on the strings...looks weird to me) He doesn't understand the proper grip for holding the racket, he questions it's logic, and I cannot explain the reasoning beyond, it's just better that way...I showed him how I hold my racket, which I believe to be correct, (I'm an expert level singles player btw) but he says it would look like all my shots would be slicing the bird...(which they aren't) Any help is much appreciated...sorry for the lack of spacing, my keyboard is messed up..Cheers. I am planning on posting videos of him and myself playing singles, so you can see what's going on. Might be helpful.
