Anyway, here's your solution

Too much weight

What I mean is, u want to keep your elbows close, but u can't, hence, too much weight. And like janson said, how you row, hits different parts, how you grip, hits different parts too.

Damn. Raw!??

Chiropractor is not tit dar. They are certified, qualified practitioners in chiropractic field. Spine and Join specialist is all over Malaysia. Go and visit one.

It is either a compound movement or an isolation movement

.....

those who do xray are not doctors, those could be medical officers, doctos are either orthopaedics since we're talking x-rays.

A chiropractor need NOT see an X- Ray. Open up yellow pages and give one nearest to you a call, go for a session then you know

Pardon me if I got it wrong, because from when I went for my Xray and MRI for my shoulder previously , those who conducted it weren't doctors.

I think he meant muscle soreness

You going to failure with your sets man? Enough intensity? Ignore what weight your friend does, you use weights that bring YOU to failure. It is YOUR body you're training.

List your workout here mate. How long have you been following the routine? How are your progress?

Shoulders are really difficult to really feel sore unless you got it right with the intensity, your traps and back, do you squeeze at the top of the rep ?

Apart from that, how long have you been on this routine? It might be just your body getting used to it.

Holy shit, this is hard to read on my phone. You do this every workout man?

Or he has really poor form and wrong intensity.

He could say he's curling 30lbs, but If in actual fact he is dancing with the 30lbs. He ain't gonn get no biceps worked. Lol. Just saying

Focus on the squeeze and contraction of the muscle being worked. Never throw the weight up, use the specific muscle to work the weights. Dont let the weights control you, you control the weights

Get a proper trainin split. Why you doing DTP so early on? And it's not meant to be used like this

Exactly man.

Follow twinmuscleworkout and scotthermanfitness in YouTube. Read on the DTP link I posted few pages back. Understand the concept before using it. You would learn how to drive and how the components work before you drive , why not do the same here?

And I suggest you join a proper gym bro.

Pulling Movements, when you pull down, ARCH your back and squeeze your shoulder blades together.
Rowing Movements, again, ARCH your back and squeeze your shoulder blades together

NEVER use momentum on your weight lifting. Always control the weight on the negative portion of the rep , Explode on the positive portion but NO MOMENTUM USAGE.

The lats CANNOT contract if your back is not arched. And besides, if you round your back training back, you're bound to be screwed.
