Breathing while bending forward can help you breathe more easily while you are exercising or resting. Lean forward at the waist, and keep your back straight. People often use a table or the back of a chair for this. You can also use this breathing method while you are sitting down.
Pursed-lip breathing helps you breathe more air out so that your next breath can be deeper. Breathe in through your nose and out through your mouth while almost closing your lips. Breathe in for about 2 seconds, and breathe out for 4 to 6 seconds.
