You're welcome,
@Jose Manuel. My orthopedist tells me that, based on the imaging that's been done to my shoulders, he's surprised I raise my hand over my head, but somehow I manage. You know, Pavel's most recent article here,
Seven Steps to Strength: Programming as a Science Experiment | StrongFirst, contains some very wise words throughout, but these at the beginning struck me most:
While the article is about programming, the same is true of technique. One of the greatest, and arguably _the_ greatest powerlifter of all time, Ed Coan, talk about this in some of the videos you can find on YouTube, and often in response to questions like, "What should my stance be?" about someone's deadlift or squat. He answer is always along the lines of, "Find something that works for you, then keep experimenting in small ways to see if you can improve it." I owe my recent lifetime deadlift PR's at age 67 to his advice because I found that a slight change in position to my right foot - we're talking about maybe 1", maximum - allowed me to pull more weight and, not only that, it felt better, too, the proverbial "win/win."
I have worked out my own cues for being able to do overhead work and, while it's far ideal - ideal would be shoulders that weren't diagnosed with "severe arthritis," I get by OK. And I'm still experimenting, still learning, about what it is that _I_ need to do in order to do overhead work, and I'm still improving.
