Google "super cropping" then video. There are dozens of videos. And hundreds of general articles and discussions about it.

You want something already tested?

Try what you saw. It's easy and don't be afraid of being too rough with them. I broke a main stem when trying my first time. It was so severe that the limb just hung upside down. I just propped it up with a stake and now its massive. Squeeze a branch and feel it. Now rotate 1/4 turn and try again. You'll feel one is a lil softer than the other. Squeeze the soft side and slowly rotate while bending. You may get a small crack on the branch or see some moisture coming out of it. That's it! Now give her a few days to recover and then you'll see lots of new growth.
