Why when you box and don’t breathe out you feel more tired than when you breathe out

Answer 1

I’ll assume is because of oxygen. I’m no doctor but I’ll put my two cents in. When your exhaling you’re getting rid of oxygen in your lungs. Oxygen makes your muscles (and the rest of your body) function so if you hold your breath, you’re losing oxygen and carbon dioxide builds in your lungs. So when you exhale you’re getting more oxygen in, rather than just holding that and carbon dioxide in your lungs. That’s my guess I’ll go now
