Wibowo Hadisubroto on Instagram: "the concept of “brushing” the ball is a common way to describe the low-to-high swing path for generating topspin, where you’re not just hitting through the ball, but also brushing up the back of it. To do this effectively, the racket head should start below the ball’s contact point, and the strings should make contact with the top-back portion of the ball as the racket moves forward and up #tenniscoaching #tennistips #tennis #wibowohadisubroto #tennistutorial"
