Can someone explain pack stretching to me.
Packing was taught to me by Eric Fattah, and it goes something like this:
Open your mouth and fill it up with as much air as possible, then close your mouth. Now open the"valve" to your lungs and push the air into your chest, while bringing your chin towards your chest. Close the valve that goes to your lungs. Keeping your lungs closed, open your mouth again while lifting your chin upwards. Fill your mouth with air, close your lips, then open the valve to your lungs again, chin towards chest, pushing the air into your lungs, then close the "valve" again. You have now done 2 "packs". Keep doing this and you will notice that your chest begins to expand as the pressure and volume builds in your lungs.
There is of course a limit to this, and you must be very careful. I have heard that practitioners have damaged their lungs, but never seen it happen. Any stretching in any part of the body must be slowly worked up to over a long period of time, and the lungs and chest are no different.
You can try doing a number of packs, then stretch your chest and torso in all directions while holding your breath with the extra "packed" air. Be careful, as packing can cause the blood pressure in your head to drop dramatically, causing you to pass out. Do it on your knees if you are feeling as if your blood pressure is low. Take your time and be careful with yourself

Good luck,
