To anyone who hasn't come around to filming themselves performing the exercises, definitely do so TODAY. Many of you will be astounded by your bad form and mistakes, I guarantee it. It's astounding how unaware one can be of one's own movements and form without a coach.
I did film myself today for the first time, and I am horrified. Seeing how far off I am with my Xiaopengs, how lame my simple pushups are... I've made a decision to start over from scratch, and make sure I perform every single exercise flawlessly. My chances for progressing further are slim to none if I don't correct this as soon as possible. It sucks to start over again, but that's life.
So to restate to all beginners like me: Do film yourself and compare your form to those in the videos.
