Claudio,
You lifts look pretty good.
You are doing two things we want to see improve:
Start in a better position. Your back is a little round. Try to get it flatter.
And, you are locking out a lot with your lower back. Try to use your legs and glutes more.
I’m sure they mentioned this at Training Day.
I suggest the following for lifts at the meet:
Open: 205
2nd: 315
3rd: 325-330
