With the recent Hummingbird change to search, I would concentrate more on making the title say exactly what your content includes. Instead of concentrating on keyword placement, think more in terms of answering a search query asked by a human. With the above example, someone may enter a voice search on, "how can I breathe better, find tips on best breathing techniques". An effective title could be as simple as How to Breathe Better With Your Next Breath or Best Breathing Techniques for Better Health. If the content includes the best information and successfully answers the search query, the best technique for titles is to write for a human.
