Form check ; Squat, Deadlift, Bench Press

[seanprok]

I've been making good progress with all my lifts except for my squat. There has been a couple of workouts where I've had bad lower back pain and I can only assume its due to improper form. If someone can take a look and maybe give me some pointers on what I might be able to do to improve it would be greatly appreciated!!

Also would like to know if this is good form for these :

Squat:
The squat to me looked like you could have moved the bar down on your back the tiniest bit, and had a more horizontal back angle, hips back more. Also, your eye position should be pointed 3-4 metres in front of you, it looks like it might be affecting your hip drive.
The rack looks like it is set 1 pin too high on setup.

Bench:

Need to Arch alot harder, and possibly touch 1 inch lower on the chest. Can't quite see from the video. Your moving your legs around between reps, they should be used to push your arch up and be firmly planted on the floor before setup. Try keeping the shoulder blades together tighter too.

Deadlift:

I'd ditch the rubber matt and shoes. And point your knees out, so they're just touching your elbows on setup.

Squat: Kill off that box you're using for depth. It's only a crutch and you need to learn how to gauge depth without it. Otherwise these are fundamentally clean. As per aaron's post, check the hook height and consider dropping it one notch. I'd also second his advice to try a slightly more head down position.
