Most club players can’t train 40 hours per week due to family commitments, school, job, etc… However, most players can dedicate around 10 hours per week to improve. For my personal students, I ask them to work hard to produce the best possible 10 hours that they can do. I ask them to do 4 hours of matches, 1 hour of serving practice, 1 hour of physical training, 1 hour of video analysis, and 3 hours of training with the Newgy Robo-Pong 2050 robot.
