They are just from my cell phone, don't you train at the gym where you work?
I'm not sure where you are looking in her squat. Rox is doing OL for 3 years and she's pretty flexible, from what I've seen. She can do a technical squat with 80kg plus a few metal plates, and that's ass to the grass. At the bottom, I try to push my tailbone to the floor to get a low as possible. It helps to get that low, your legs can shoot you up faster. Although it is possible to get too low. I actually folded myself up in a clean at the bottom so much I almost didn't make it back up! I think it's on video somewhere.
Those are the shoes I was talking about. They make a huge difference for stability, Chucks don't even come close, or any other running shoe. They have a really solid base and a wedge that helps you get as low as possible. Since I got them, my training improved 100%.
