for my own reference, approx. 18 months later, since about 2 weeks ago, I've made a significant increase to the weights I'm using on the gym circuit I use. so far, so good. I do favor the left shoulder as I make the 1st lift getting the bars up from their resting place, but then use both shoulders equally during the set

currently dealing w/ a strained back that came out of nowhere & using muscle relaxers, so will be taking this week off from the gym, I think. gotta settle everything down
