hey well i started baddminton 5,6 years ago some days ago my style changed like im playing tennis! moving the racket like that...and all....i literally never have event ouched a tennis racket....why is it?
Maybe, you hurt your wrist or elbow and that's why you've subconciously changed your swing. I gather that it is not good if you locked your wrist and elbow (ie tennis style) in badminton.
