I started playing piano not too long after I started climbing. I progressed very quickly to the 5.10 and 5.11 level and didn't really seriously start playing piano everyday until I was well into the 5.11s. Sometimes there'd be some fingernail crimps put in with some of the routes I'd be training on and I noticed that two of the fingers in my left hand were getting sore while all the others felt great. I didn't realize this at first, but before I started playing piano alot all my fingers would be sore after some routes focusing on hard crimps. After I really started playing there was only the two that were still getting sore and this was when I realized the piano was helping my fingers out alot. Those two fingers were still getting sore because for all the songs I was playing I almost never used those two fingers. After this I learned some songs & scales to involve every finger and since then ALL my fingers have always felt good.
This really isn't soo helpful though. If it's not a passion for you then you probably won't stick with it. But if you're sitting at home for three months because of a finger injury, maybe it could help you recover faster +
