A cross over at the front of the stroke tends to cause your elbow to drop, also damaging your catch and hurting your propulsion.
身前的划水过中线易于使你的肘部下沉,而且破坏你的抓水和损害你的动力。
At full reach and without dropping your elbow, feel like you are tipping your finger-tips over the front of a barrel (again flexing at the wrist), which will start the catch.
在完全前够并且没有沉肘的时候,感觉好像你把你手指点到了一只枪管的前段(再收一点手腕),这就是抓水的开始。
