[Cthulhu_]

I had a Kinesis Advantage some ten years ago at my first job, as well as a vertical mouse; they didn't work for me in the end. Good keyboard, but it didn't fix my RSI issues.

What did help a lot was a Mac wireless keyboard (flat profile) and weight lifting, especially deadlifts that at first I couldn't do much of because of grip strength. Couldn't do pushups either due to wrist pain. But my grip strength quickly improved (I could do without the grip straps after just four or five sessions) and the wrist pain went away.

It's making a comeback now though, I've been working on a regular keyboard for a while due to working from home and haven't been in a gym for months now.
