Throughout the week since then I started allowing myself to use the Moonboard again - starting with only V4 or V5 on the first day, and gradually working up to V8/9 more recently. Because I am trying hard to keep my shoulder engaged I don't quite have the full reach on my left side yet and the whole shoulder area gets pretty damn tired after an hour session. I have been mixing this with also slowly re-introducing one arm hangs on the left side. About 10 days ago it felt too aggressive to hang one arm with my injured shoulder but slowly with the use of stretchy bands as aid I got back to body weight on rings, and then body weight on a 30mm hold and eventually 2 days ago a 20mm hold! This is quite good as my 'hard' hangs are usually on a 17mm, so, pretty close to where I was before.
I assume that the final 15% to full recovery will take some time yet, but my primary aim was to have a good shot at a big fall season and that is seeming totally possible, so I am stoked. Wish me luck!!
