Purse lip breathing
This type of breathing exercise helps more get in and out of your lungs. You can do this simply by breathing in through your nose, and breathing out your mouth with pursed lips. The key is to do it slowly and steadily. This helps keep your airways open for longer, and allows you to inhale more air.
Belly breathing is a breathing exercise where you train your diaphragm to take in more air.
To do this, place on hand on your chest, and another hand on your belly. When you inhale, make sure that your chest doesn’t move, and you use your diaphragm to breathe. You should feel your belly move as your lungs get filled with air.
When you exhale, you should do so using your diaphragm as well, and you should be able to feel your belly become smaller.
This type of breathing is ideal because it maximizes your lung capacity, and allows you to take in more oxygen compared to breathing by puffing up your chest3.
Relaxed deep breathing
This breathing is similar to belly breathing, and you can even do it while doing belly breathing. To do relaxed deep breathing, you’ll need to relax your shoulders and avoid tensing up any part of your body. Next, breathe in deeply, and as slowly as you can. Try to keep it as smooth and relaxed as possible, and then slowly breathe out.
