Even though I've been playing for about two years i have a horrible habit of not fully extending my racquet before a swing. Any tips on how to fix? Example: Elbow is bent while winding for hit such that the racquet is pretty much above my head as i go in to return. The result is that hardly any of my smashes end up going over the net. I play in high school level.
You need to be able to comfortably hit strong clears before you know how to hit smashes. Then the smash is a matter of getting the strike point to be above you and in front of your racket shoulder by 8-12 inches and you power downward from there with forearm pronation.
When hitting a clear then, should i strive to have full extension of my arm? Basically that's my problem i guess. Arm extension.
Great! Btw this is a great website by Gollum on this forum. A lot of excellent useful info. http://www.badmintonbible.com/articles/forehand-power/
