A familiar slogan that many people say:
“Practice makes perfect.”
Sorry. That is not true. Practice does not make perfect. Rather, swimmers and coaches know this updated slogan.
“Perfect practice makes perfect.”
When practices happen and mistakes are constantly made, seemingly by design, then the athletes and the team is forming bad habits. Bad habits are hard to break. It is far better to start with good habits and good technique and always strive to improve performances without getting sloppy.
