斯瓦泰克!多哈1000赛媒体日!Iga聊了聊自己发球这方面的一些训练:'Getting the toss more stable, and twisting more…There are some different (things) that I'm doing, but at the same time moving the elbow more back or getting the hips more''I’ve been working on my serve, forehand, and my footwork'也就是抛球要更稳定、手肘更往后点、多用点屁股……最近主要就在攻克发球、正手和脚步这三方面wta
