Intermittent elbow pain

I have relatively little muscle in my upper body.

In the past, there were cracking sounds in my shoulder and elbow joints, and my muscle strength was very weak.

I developed a severe rounded shoulder posture, and even a little strain would cause discomfort.

Since then, as I continued strength training, my shoulders have also loosened up a lot and improved a bit.

When doing upper body exercises like seated rows or lat pulldowns, I tend to rely on my arms because I lack strength.

Every time that happens, especially the right elbow bends or severe pain occurs.

I'm trying to reduce weight and carry lighter, but to build muscle, I need to lift heavier,ㅠㅠ

Even after receiving physical therapy and posture correction, it recurs again after a few months...

It's too difficult,ㅠ
