백핸드 드라이브 공에 정면을 굴린다는 의미는?? 탁구레슨 이순우코치

Just like forehand, backhand also has many ways to roll the ball by hitting the front of the ball. I swing the ball upward to hit it stably. Coach Lee Soon-woo tells me to slightly twist my elbow to hit the front of the ball (hit the ball from behind and swing it forward). Pan Zhendong, Ma Long, and Harimoto are representative examples of twisting the lower arm to send the ball heavily. What do you think it looks like?
