Don't try and clear the wake right away. Make sure your are edging all the the way through the top of the wake and you're keeping the handle close to your hip. From there start with small jumps where you feel comfortable while still using good form. Once you feel comfortable jump a little further and so on until you clear the wake. I discourage people from trying to clear the wake right from the get go because I think it leads to bad form and taking unnecessary hard falls.

Make it a point to jump heelside and toeside back and forth everytime you ride.
