Every sport skill has a basic technical model that a beginner can master in a relatively short time. What is the difference then from that and the master – the Roger Federer in tennis, Usain Bolt in sprinting, Simone Biles in gymnastics or Michael Phelps in the pool? What makes them masters of their craft? Certainly, they have refined technique, that is a given. The longer I coach and the more I reflect on this I am convinced it is rhythm and tempo.
