Actually I'm pretty impressed with her form.  Her toes are pointing in the right direction.  If your feet are too straight your knees will buckle in.  I also don't understand the hate on the light weight.  It's so much better to start light and build up rather then just try and lift heavy ass weight.  I just recently hurt my knee trying to lift 260 while weighting 165.    My friends just kept egging me on and I foolishly kept going after lifting 250.  Other than that she needs to go on a fucking diet.
