Boom. If you actually think about extending to the point where you're standing perfectly straight with your arms out, it looks super dumb but its a great training technique. This guy is upside down, but this is the idea -
Literally blast off the takeoff jumping super high and completely extending your body. You can drop the lame super stiff extension later, but doing it for a few days will get you the idea of what you need.
You'll also notice that you'll go bigger when you pop properly. So be careful and adjust your speed accordingly.
