Deadlift Form check (rounded back)
Yesterday I did tried doing 1 set of 5 reps for Deadlift at 170kg (375lb), however I did 2 reps and stopped as I felt my back was rounded. I then rested for a bit and attempted to try to get 3 reps, My first rep felt like my back was set (but it was round) and I started my second rep and felt my back unset and so I stopped the set (was kind of frustrated) and I then rested a few minutes and did 5 reps at 120kg to see if my form was better with light weight, but it was not.
