4. Versatile Use: A kickboard without holes can be used for various swimming drills and exercises, including kicking drills, streamline practice, and upper body strength exercises.
5. Color Options: Depending on the brand or manufacturer, the kickboard may come in different color options to suit personal preferences or match other swimming gear.
