The only way I know is the standard way, using backhand thumb grip and slightly pushing the racket forward, as is taught in the videos by BadmintonFamly and other coaching channels. But then I see the Korean player at 1:00 pushing racket-head forward AND turning it around (maybe by supinating his forearm...idk). Check the video in slow-motion at 1:00. Can someone guide me to the finer details of this method of low serve, and also its pros and cons? If there is a video out there about this style of backhand low serve. I would highly appreciate it.
