[mike1]

hi this is another form check on my deadlift

i did 108kg x 5 last week and noticed alot of upper back rounding which is obviosuly not very good shown here

i lowered the weight today to 105kg x 5 but im still not sure if my form is good.

i have poor posture anyway but i dont want to use this as an excuse to do deadlifts wrong, but its making it difficult for me to assess whether my back is rounding due to bad technique (and thus lack of upper back strength) or just due to my current posture.

i also include a warmup of 80kg x1 if that helps

IMO, your back looks fine. There does not appear to be a significant degradation from your warm-up set to your work sets. Yes, there is some rounding in your T-spine. You also look like you might have some kyphosis (rounding) in your upper back when standing without load. Maybe try some T-spine mobility drills (for example, trying to extend your upper back while lying over a foam roller), or add in some Kroc Rows at the end of your workout as some additional strengthening for your upper back. Also try to use a more neutral head position (head aligned with spine versus looking straight ahead).
