How to Breathe During Exercise
Strength Training
Like cardio, strength training increases the body's need for oxygen and automatically results in a faster breathing rate. However, many people have a tendency to hold their breath during strenuous activity like weight lifting. Known as the valsalva maneuver, this can limit oxygen delivery to the brain and cause dizziness, fainting, a spike in blood pressure and other complications. During strength training, the most important thing to remember about breathing is to just do it! Never hold your breath; be aware of how you are breathing at all times, whether through the nose or mouth.
