Form checks!

[paranoidandroid]

G'day folks, i'm in my 2nd wk of SS and have read the book in full. I understand it'll take me a while to perfect these movements and i'm wondering if some of you experts would be so kind as to throw me a few pointers if you have a couple of minutes free! It's hard to reproduce these lifts in the gym just from reading text whilst half asleep in bed the night before..
Today was Bench - Squat - Deadlift and i took some vids.

Bench


I'm struggling a bit here - it was my final set


Deadlift - this was the set before i started the workout set.


Any advice whatsoever would be fantastic.

Thanks in advance.

Oh and theres a vid of my squatting during my last workout



(i've only just read the sticky which covers posting videos for form checks - all points duly noted for next time!!!)
