Sam,

I am happy to have you aboard.

Let’s look at your training.
1. Squat:
As you begin the descent, you go right into a slight spinal extension.
This indicates one of two things.
Losing your abdominal brace or poor initiation.
I am going with a little A and a little B.
Brace the abs down and then open your knees-push hips back.
Try not to arch it down.

2. Good mornings look pretty good.
Next time try moving by forcing the knees out & hinging hips back as opposed to bending back.

3. Bench look pretty good. I’d suggest trying to get the hips more involved.

4. Keystone DL
Try to keep your neck neutral-don’t crane it back.
And at lockout, simply stand straight up, try not to drive the hip too far forward.
JL wrote about his in the t nation article.

Overall you have a good solid base to begin with.

Let’s get to work!
