Many times we see tennis players motivating themselves on court, with phrases like “Come on!” or “Got it!”. Or we see how they give instructions to themselves, like “Fast!”, or “Position”. Is this useful for players? Do they do this in an instinctive way, or do they learn how to do it? Normally, these kinds of techniques are part of their training and the mental work they do, which every day becomes more and more important in the professional tennis world.
