What breathing techniques do you teach your clients?

My clients love the emphasis on breathing, both throughout the workout and at the end! It seems odd that such a thing would bring about so much satisfaction, but I think it stems from the fact that most people nowadays breathe very shallowly (is that even a word??). I encourage deep breaths (deep, slow inhales and exhales) and belly breaths, where appropriate during the workout, and incorporate stretching, torso rotations, and head tilts (front, back, side to side, and over shoulders) at the end of the session. Funny, I’ve had so many people remark that it’s the only time during their day where they actually stop, breathe, and relax; and they LOVE it!!
