A "catch-up drill" is a training exercise designed to help individuals or teams improve their skills and performance after a period of inactivity or lagging progress. This type of drill often focuses on reinforcing fundamental techniques and strategies, ensuring that participants can quickly regain their previous level of proficiency. In sports, for example, a catch-up drill might involve practicing specific plays or movements that athletes have not executed recently. This helps them refresh their memory and build confidence before returning to competitive situations. Overall, catch-up drills are essential for maintaining readiness and enhancing overall performance.
