Squat check

[Nate9]

Hi, looking to get some input on my squats.
On the second rep I kinda relaxed at the bottom, in the following reps the bar went shifting to the sides, the shifting kinda happened on the previous sets too, although to a lesser extent.
Any input on how to get a better squat will be appreciated, thanks.

Stop arching your back so much. Your chest should be pointed more at the ground instead of the wall in front of you. Keep your chin down. Go a little deeper.

Thanks Tom, how does it look now?
I have also been experiencing distal bicep pain on my left arm after squats, I have been setting up like described in Nick's article (here) that fixed things for a while but today it came back a little, do you notice anything wrong with my grip?

Fourth rep is your best. My previous comments still apply for the most part, although some of your reps were deep enough. You may be overdoing the knees out a bit. Drive your ass up. Don't lead with your chest.
