That is good to ear.
I am making a concerted effort to relax every morning, and every night before I sleep. It is just for a short time - then I enjoy the moment. I am getting better at it and it is lasting longer. I was getting frustrated before, because I would get one bit relaxed and the previous bit would clamp up. I am having to relearn.
I think I have been holding my diaphragm tight, so that I appear to be resisting the last bit of breathing out, and the first bit of breathing in. I also try and breath and relax this during the day if I notice I am breath-holding.
So far, it seems to help. At least, when I start to feel it relax, I can welcome it and it feels nice.
I have done yoga off and on since I was a student. I cannot remember anything properly without a class, but the breathing awareness/relaxation awareness is really worthwhile.
