How do you jump hurdles correctly?

I've never really been told how to jump them but coach wants me to. But my main question is do you jump of the same foot each time, or do you switch eash time.|||Most hurdlers lead with the same leg every time because it helps to keep your steps consistent. It does help to get good at using both legs though that way if your steps get off you wont have to studder step to get back on track.
