The book : Oxygen advantage[1] makes similar points.
It points out to the research of why swimmers have higher life expectancy than the average athelete, why almost all of us are hyperventilating. Then he outlines simple exercises to improve your breathing habit.
Few points:
1. Always breathe through your nose. Even when you are jogging/cycling heavily.
2. Try to hold your breathe for elongate period of time.
3. Try doing 2 while walking/running/cycling.
4. Swim!
5. Pushing the breathe out and then holding is better than taking the breathe in and holding.
