Edging is moving heelside and toeside within the wake. In order to edge you need to apply pressure on your front heel or front toes to move in the direction you want to go. Remember to keep your arms relaxed. Put pressure on your front heel to move to the heelside and put pressure on your front toes to move to the toeside.
CROSSING THE WAKE
Once you are riding and want to cross the wake, start by turning your shoulders and chest so they are more open towards the boat. Keep your eyes focused on where you want to go. Once you are comfortable edging within the wake you can cross the wake. When you approach the wake continue to hold the pressure on your heels and toes, keep your knees bent, arms relaxed (don't pull the rope). Use the same technique to cross back into the wake. If you go out on your heels you will have to come back into the wake on your toes. If you go out on your toes you will have to use your heels to get back into the wake. Common mistakes the beginners make is trying to steer with the rope, don't do this, just hold the rope in a comfortable position.
Switch riding means to ride with your non-natural foot forward. You will want to attempt to edge within the wake on your switch and slowly progress to crossing the wake. Switch riding can be hard at first, because it doesn't feel natural. The more you ride on your switch the more comfortable you will feel. Focus on relaxing your arms and using your front foot to direct the movement of your board.
Start off on your heelside edge, to get a good ollie you will need to push your back leg forward towards your front leg, as always its important to keep your arms relaxed. Once you nail the heelside you can move onto toeside by doing the same thing.
ONE WAKE JUMP
Start by edging out on either your toes or heels, let the rope pull you towards the wake and face where you are going. You will want to edge into the wake. You should put more weight on your back leg, and then lift with the front as you hit the wake. This will allow majority of the board to get airborne, leaving the back part of the board in the water. Once you lift that front foot, begin to shift your weight slowly back to that front foot, while tucking that back leg to your hips and bringing that entire board out of that water.
