相比良好的滚身，这个拉水过程带来一个有效的长划臂技术，但这个并不长得过度。

很多人不愿意这样做，他们认为伸直肘部更有利。但是我这个练习会让你喜欢长划臂并拉长体形。

试着每25米用2个水下长划臂加上水面的完整划臂，再加上两个水下长划臂总共6个划臂动作完成，这个练习能让你达到最大的划臂行程。

2 pullouts underwater + 2 full strokes on the surface + 2 more pullouts underwater ( 6 total strokes ) , per 25 . this drill forces you to get the most out of each pull.
