The fingertip drag drill is one of the more straightforward and simple drills to master. While swimming freestyle, keep your fingertips grazing the surface of the water as you take your stroke. The underwater pull will be in the normal fashion, but as you are breaking your arm from underneath the water you should keep you fingertips down on top of the water and position your elbow high in the air. This should slow down your stroke rate slightly, but for the most part will look similar to a normal freestyle stroke.
By forcing yourself to keep the tips of your fingers on the surface of the water during the peak of your stroke recovery, you are helping yourself to master the correct high elbow and body position of the freestyle stroke. Often, particularly in younger athletes, swimmers will throw their hands high up towards the ceiling when they swim freestyle. The fingertip drag drill forces swimmers to keep their elbow in the correct position. A swimmer's hand should never reach higher than their elbow. This drill also helps swimmers refrain from "slapping" the water with their hands thus catching a lot of bubbles under the palm of their hand. For the best results in freestyle, the fingertips should enter the water almost splash free and be relaxed throughout the entire recovery cycle.
