Walk into any fitness center, exercise arena or weight-training room and you will hear a lot of heavy breathing. It is an essential element in lifting weights because breathing properly will increase the effectiveness of the workout. Breathing improperly can lead to high blood pressure and sometimes serious medical problems. Any person who lifts weights or performs similar resistance training needs to learn correct breathing technique.
Breathing is a task that involves some of the back muscles, which is why pain in the upper back when breathing is often a sign of a pulled or sore muscle. The upper back muscles may be injured, though lower back, abdominal, and diaphragm muscles are also often affected by every breath.
