So, at the gym, instead of bypassing it entirely, we dug into back work with only a few modifications. No pullups at all, and went light and "super slow" and didn't as back as far with all the assorted rows.
And a new exercise. Dumbbell lateral raises. Grip two dumbells, one in each hand, with the elbow bent at a right angle so that my fists are pointed straight forward, arms at my sides. Now lift and rotate my arms, so that the elbows for the ends of a straight line going through my shoulders. That discovered whole new avenues of weakness in my shoulders and back.
Even so, was glad that I was able to work it.
I wanna go JUMP!
