A few questions:
As a point of background, I realize that the more humbly I step back and try to go back to the basics of this move, the more I realize I have more to work on. Currently, I still have a lot of anterior deltoid pain in my right shoulder. Furthermore, flexion in my arm (raising it up in front of my body to overhead) is difficult and uncomfortable to me.
Should I use this move as a warm-up every workout? I use a 6lb. bar and it was difficult, then I used a 5lb. bar and it's still difficult. Should I go lower to say 2.5lbs? With raising the arms overhead, do the traps/thoracic area contract in order to pull the arms/shoulders behind the head? Are there are any stretches SMFR (self-myofascial release; foam rolling) that I should do? Alternatively are there other stretches or methods I could use to improve this more effectively?
I currently do HS/PE2 and PE1-im and PE2-im. PE2 I have worked up to 5x36 seconds. I was doing PE1 but was able to do 5x90 seconds and also was incorporating tuck positions (out of boredom), so I moved on to this. PE2-im is also problematic for me, and I will lower the weight I am using. I have also been working on PE2-im for a much shorter time, so I am not as concerned with these as I am with PE1-im. The reason that that is is because I have some slight discomfort outside of my workouts with shoulder flexion. Hopefully, the questions and concerns were clear enough. Hopefully, people on the forum have some guided advice for this, too.
