How do I put on mass in these areas? It's all bony and shit. I do rows but it only seems to hit my central and lower back, as well as my arms.

deadlifts, rows, rear delt flies
>I do rows but it only seems to hit my central and lower back
doesn't matter what they 'seem' to hit, they objectively work your upper back tremendously

This.

Also
Upright rows
Lateral raises
Shrugs
Rack Pulls
Up right rows with cables

Ignore the DYEL faggots above me. All you need to do is OHP.

there's no muscle in those areas.

Traps have multiple functions
Rows
OHP
Deadlifts
Cleans

>Traps
No, I mean like the back of my shoulders

bent-over lateral raises

Posterior deltoids?

Rear delt flies, pull aparts and face pulls are the way to go (in addition to rows)

I've already told you the only real answer, there's no muscle there - look at anatomical diagrams of the back muscles, it's exposed bone.
