Squat form check

[bodhibrouwers]

Hello, I have learned a lot from Starting Strength over the past years, but I made the stupid mistake of avoiding the squat because around 220 lbs my elbows would start to hurt and I couldn't keep my upper back tight.
After hours of listening and reading content I really made a commitment to be able to get under a heavy squat so I could put all the valuable teaching into practice.
I'm very happy to report that I made it to this point where I can pr (3x5 254lbs) pain free. I switched the grip, kept the focus on my upper back and made sure to keep driving with the hips.

Is there anything I could improve on (maybe with a light day + 1x5 heavy deadlifts on wednesday or just go up three times a week)?

Thank you very much, keep up all the good work you do,

Greetings from the Netherlands.

Are you supporting the weight of the bar with your arms or with your back?

With my back. I messed this up in the past, resulting in a break of thoracic extension and later elbow pain.
Switching to thumbs around grip seems to work for me.

My cue every rep is now full extension, breathe, hold.

Just hit a 5lbs pr

Here is the last pr.
Any suggestions are appreciated.

I only asked because your elbows were quivering on the descent. Sounds like you fixed it though. Squats look good.
