This is excellent advice. I still play sport at a high level at the moment and being 6'6, I was getting back pain. Superman, plank and bird dog are all excellent exercises to help strengthen your back and core. Since I've been doing them, I've alleviated all the back pain which I used to get after training and matches. The only thing I'd say is that the plank exercises may not be the best exercises for people with a reall weak core. You may want to start at something lower (bird dog and other light core exercises might be better).
