I've not had any posture or RSI problems, but here comes that word: YET. A few people have commented that whenever I stop typing I like to stretch my arms right down to the fingertips and adjust my position on the chair, sometimes getting up completely and straightening my clothes. It's an unconscious habit so I find it hilarious when people point it out but that could be something that has helped me. These sets look very familiar to me as similar core exercises to ones I've done as part of rowing and yoga, but there are a few new ideas here I can't wait to try. Thanks!
