Joe,
1) there are no “perfect” or “must-have” exercises
and 2) every person’s biomechanics/musculature are different
However, I have an “on paper” program question. Are there any key exercises “on paper” you would want to implement (if someone could physically do them) to bring up mid-trap/mid-back thickness? I’m sure deads/RDLs are a good option. It’s what I’ll be prioritizing this next push up, so I’m trying to be optimal.
Much appreciated, as always!
