And that is where my setback, my "two steps backward," has occurred. I recently moved up to 80 pounds from 70 and it didn't seem too bad - until Wednesday night. About seven years ago, I partially tore my right rotator cuff, and now I am having very similar pain in my right shoulder. It is not agonizing - and in fact, I've had more or less continuous low level pain in that shoulder for seven years - but it is pain that was not there before this past week. And it should not be there. So clearly, I have done something I didn't want to do.
So what to do next? I think I need to knock off the upper body for a week. Then try a few light weight, say 50 pounds, workouts and see how that feels. Or even 40 pounds, or if need be just 30. I probably need to focus on lighter weights and many more repetitions. I am not sure how best to do it, but it does seem that this particular fitness goal may be one that I need to back off of.
It is always discouraging to have setbacks, but they are part of life and we just have to do our best to move forward, even if we don't get quite as far as we hoped for.
