Additional Information: Recently started to do starting strength again over a month ago, and I'm planning to keep on going until the end of mid-June; mainly due to compulsory military service in Finland. Right now, I'm residing in Hong Kong and doing my internship at a gym.

The video below is a working set of my deadlift at 172.5kg (380lbs) for 5 reps. Really it was 4 reps as I had to reset for the final one, but I'll let you guys be the judge. Also my warm-up sets were done from 60kg (132lbs) for 5, 100kg (220lbs) for 3, 120kg (265lbs) for 2, and 150kg (330lbs) for 1.

My concern is that if I'm not setting up properly and having that much of a rounded back is okay for a 172.5kg deadlift. I'm thinking that I should bite the bullet and just reset and go down 155kg and get my back stronger.
