It is very healthy to practice deep breathing Xtreme Muscle Proexercises when outdoors. These should be practiced by breathing slowly through the nose and not through the mouth. An oriental deep-breathing exercise is to press on one side of the nose with one's finger, to close one of the nostrils, while breathing at the same time through the other nostril. By paying attention, we can know by the slight sounds of the air passing through, if the breathing is regular or irregular. These breathing exercises can be done at about three breaths per minute, and then slowly reduce it to maybe one or two per minute. Deep breathing in itself is a fantastic exercise if done slowly. Forced rapid breathing can be harmful.
