Rather, aim for good form and regular effort over time, not intensity. The weight you move isn't as important as how you move it

Look into face pulls, aim for volume and posture over weight

No, it won't. Practice doesn't make perfect, *perfect* practice makes perfect. And how one carries themselves during the other 12 hours of the day will have more of an impact.  Yoga is a process of awareness, not a cure

Yoga my guy.

It's general, and will correct your issue.

You can improve it.  A lot of it will come down to staying diligent about holding good posture throughout the day. Exercises can't substitute for that.

Your typical bicep curls, shoulder press, upright rows, squats, lunges, etc. Of course spread throughout the week. The mains one that I’ve been trying for my back are bent over rows and deadlifts, like 20x4. And right before I shower, I do some chin tucks, 10x3.

That's awesome! I hope you prove him wrong!  
  
So what are you doing in your workouts?

I have only met him like 5 times. Other than those 4 times, I never went to him for this issue. My parents have us under some sort of government-funded insurance, so I don't have access to those quality doctors.  I've been working out since the beginning of last month, and I'm here asking for advice so I can input it into my workout.

Sounds like your doc doesn't have a lot of faith that you're going to make any kind of real effort

Im unsure about the protrude part, but i experience slight discomfort every time I look up (between lower neck and upper spine). I can move my shoulders just fine. Im also slightly underweight so they aren’t round.  The hump also has a slight curve that show my bone a little. Assuming you said “used to”, how did you correct it?

My spine used to protrude as well between my shoulder blades. Uncertain if it would be considered a dowager hump or not though. Noticed I wasn't able to move most of my back muscles as they had hardened. 

Do you experience any back, shoulder or neck pain, and/or migraines? 

Also, do you find your shoulders are rounded?

It feels hard, I can feel my bone, and it’s quite visible. Perhaps it’s not a dowager hump?

If you place your hand on your dowager hump, does it feel hard or soft?

I went to my family doctor and asked for a physical therapist and all they gave me was some pain killers. Whenever I look up, I feel discomfort. This was mainly because of my severe addiction to video games back then. I understand stretching may help but is there really any way to fully reverse the hump? Specific exercises wise?
