This is vital, you don’t want to run out of breath mid-verse. There are plenty of exercises that you can do to improve your breathing, but check this out.
Breathe out quickly and steadily till your lungs are empty. Hold it for five seconds, you should feel a little bit of pain… after the five seconds breathe in to fill your lungs, suck in quickly but steadily and hold it for 10 seconds. Repeat this for 10 minutes.
Start off slow, though, because you can hurt yourself if you hold too deep or too long. The purpose of this exercise is to stretch your diaphragm thus allowing you to breathe deeper.
Do it every day, you’ll see a real difference in around 4 weeks.
