While jogging you may run out of breath, this is normal while jogging well while exercising because your body meets your new oxygen need by pumping oxygenated blood into your muscle, also your lungs work harder to intake oxygen from the air so you gasp.
Most joggers breathe in a 2/2 rhythm but while jogging slowly they breath in 3/3 rhythm, while jogging fast they breath in 2/1 or 1/1 rhythm. When asked how a jogger should breath, world renown New Zeeland trainer said”Breathe thru the mouth. Breathe thru the nose. If possible take in air thru your ears.”
Don’t forget to keep your mouth half opened while breathing. Oxygen will go in thru the mouth and nose into the lungs, then in the blood and finally in the muscles without you having to concisely manage this. All you need to do is to find a rhythm that best suits you.
