In padel tennis, Sandy stresses that the glass is a tool for making good shots rather than an enemy. Tennis players should develop confidence in striking the ball off the glass as it slows down and gets closer to their opponent, according to him.
To improve this shot for use in games, Sandy recommends players to practice it and to let the ball strike the glass rather than trying to hit it early if it is bouncing deep. He emphasizes how important it is to set yourself up for the shot and advance the ball before making contact. While admitting that making mistakes at first is a natural aspect of learning, the movie encourages viewers to put these strategies into practice.
