Juggle the ball calm, have a little spin on it. (It should spin towards you)
Kick the ball up to your waist height. Get your other leg ready to go over the ball...
Now when the ball is at its highest point bring your left leg over the ball...
Bring your left leg over the ball, and when it's 3/4 quarters over the ball, jump up.
And hit the ball with your right foot.
Try to start by launching the ball in the hands !
