We breathe everyday without taking a rest.Normal breathing rate for humans is 14-18; breathing per minute.The amount of air that normally moves into and out of the lungs during a single cycle is 500 ml in an adult person. But do you know during a forceful inspiration you can take in 3100 ml of air and during expiration you can exhale 1200 ml of air.If you do 10 forceful breathings per day air in your lungs increases by 1900 ml,almost 4 times than your normal breathing. If you do it for 10 minutes everyday,it increases 40 times, sufficient for your whole day's energy. You will always feel fresh and active.Try this out and see the magic. All the best !
