Dumbell BP and scapular retraction

[Peter_k]

I read a previous thread about getting into the right position on the bench. But there's one thing I wasn't clear on.

Do you begin with retracted shoulder blades in the standing position, or do you do it during the backwards rocking motion?

I do it on the bench during the setup. If you do it before this, you're going to have to reset them anyway.
