What levels are flippers utilized for in swim instruction?

Flippers, also known as swim fins, are utilized in swim instruction primarily for higher skill levels, which aligns with levels 4, 5, and 6 in many swim programs. These levels typically involve more advanced techniques and efficiency in swimming strokes, where flippers can enhance the learning experience by providing increased propulsion in the water. This allows swimmers to focus on perfecting their form and technique rather than struggling against the resistance of the water.

At these intermediate to advanced levels, swimmers are often working on refining their strokes, improving their kick, and developing better body positioning in the water. Flippers help facilitate this learning process, thereby improving overall swim mechanics without compromising the swimmer's ability to practice with appropriate resistance.

In contrast, the lower levels, such as levels 1, 2, and 3, focus more on foundational skills and comfort in the water, which do not typically require or benefit significantly from the use of flippers. Similarly, levels 5, 6, and 7 may also encompass advanced skills and competitive training but level 7 usually transitions into more specialized practices that might not necessitate standard flipper usage in the same way as levels 4, 5, and 6.
