I suggest anyone who is using a computer (as I am now) needs to focus first on posterior chain/ back and shoulders primarily to stop the shoulders being pulled forward in the infamous keyboard hunch. Sort out core, winged scapula and lower rhomboids first, then do the push exercises that develop pectorals, front deltoids etc, but make sure your back is always stronger for good typing and mouse posture is my suggestion
Agreed - I was using a digitizer for many years through the 90s to early 2000's doing AutoCAD and 3D work...
So, I would say that my mousing was more than any average pointing and clicking one would typically do with consuming content.
I found that my muscles in my back would fall asleep / go numb and I would need to really focus on posture and take breaks to lay on a racket ball ort tennis ball between my shoulders to massage those muscles.
Now I get comments about my posture being so rock solid straight up when I sit at my machine due to how conscious I was of my back.
Now I just do it without thinking - but really having good posture and strong back to hold up at a machine for long hours is a must.
