这个练习是为了让大家在水中的位置感和平衡感。 要求游泳者身体尽量保持一个稳定的高臀的在水面上的位置。为了集中体会这种位置感，尽量少划水 请注意他打了很多次腿才划一下水。
(The next drill to work on body positioning is called the best balance and distance drill, where the swimmer will achieve a stable position with the hips and the body line on the surface of the water, and they will only take a stroke after they achieve a very steady position with the body dolphin. )
