Hi Genuineillusion, let's help you out here, keep the foamy at this stage, let's get a few things sorted out.
Starting push ups help a little, but it's better to practice going straight from the lying down paddle position to standing in the crouch surfing position. (I do not recommend the going to one knee position as an interim position, it will become a hard to shake unworking step).
Practice your pop ups at home on the sand there is an excellent exercise called a burpee which will give you strength, speed and balance in doing this. Get your sports teacher at school to show you a burpee and your Dad to show you.
Hey any Dad who is really into surfing would be so glad to have one of his kids to surf with ( more father daughter time)
Why no one knee semi stand up? If you go to one knee it is almost impossible to get from there to standing by putting equal pressure on your hands and feet as you get up one of them will put on more pressure as you rise and the board will screw around in a sharp turn and you will fall off.
Another thing for learners that will help is to spend some time just actually learning to fully catch waves first, don't even worry about standing up just get to the stage where you recognise that you have fully caught the wave.
Why? because in surfing getting wave speed means stabilisation and easier balance.
Hey you are in the beginnings be kind to your self think about how you were when you first started dancing and how you are now, same applies to surfing. Keep your eyes open for Girls' Day Out surfing events in Victoria.
PS have a read through the rest of the forum for other tips too, and keep in mind that if your Dad is a good surfer get your tips there. Have fun
