Impact: This exercise again targets the obliques in a different direction than crunches.

作用：这个动作也是用来锻炼腹斜肌的，不过它和卷腹锻炼的方向不一样。

Strong obliques—the side muscles that frame your six-pack—are a must for Greek heroes, Olympic discus throwers, or anyone who wants to look like one.

形成腹部六块肌肉的斜纹肌对于希腊英雄，奥林匹克铁饼运动员或者任何想要看上去健硕的人来说都是必须的。
