I know that at the start it will probably feel awkward and you will fill your muscle are having to work harder (this is good for strengthening your diaphragm) but the more you practice it you?ll find it easier to do and when you feel comfortable and gotten over the dizzy sensations you can then increase the length of time you do this for, add up to 5 seconds more onto this but don?t get carried away… it?s better to do small amounts over the day than try to do it over too long of a period.

This exercise works because it helps to increase the amount of oxygen coming into your body and give the body and muscles the needed the oxygen they have been needing.
