Singing. I was part of a choir in high school and early college, but never managed to get good at this, even though I knew well how skilled singing should sound. More than a decade later, when I was really exhausted after tending to my infant child I let out a sigh of the same type that we did as exercise back in the choir("Aaaaaaaah"). To my surprise it was almost effortless despite making quite the sound due to it being more or less at the resonance frequency of the bones in my skull. And then it dawned on me. It's essentially turning yourself into an elaborate fart pillow. Of course there's much more to that in things like posture and the mentioned resonance, but I had that covered from years of training. The only piece missing was using the diaphragm correctly. Now I sing daily and while my range is pretty average, I don't strain myself any more and can do it for hours. Also the tone is just so much better now.
