easy, just lots of practice

Ditto what cooler said. Practice practice practice. If you got a coach, do a few demos for him and he'll tell you what you can adjust and what you're doing right. If you don't, make sure you know what you're doing wrong and try to adjust it. Or you can watch some professional matches and study what they do.
