Nice!
I am a real amateur in these and didn't do as many research as I should, but I have a friend who does pranajama and sometime talked about it.. so I tried myself doing breathing exercise for 30/60 mins and trying to focus on the air flow inside, collecting it from bottom stomach first up to lungs, and then backwards.
What I do is progressively incrementing the time of "in and out", starting from 5/10 secs o to 20/30 sec in, and 20/30 sec out. I have found this exercises soo powerful and they elevated my proprioception immensely.
This is my way of "meditating" and relaxing when I set myself to find some good time for me 😅
