4. Breathe through your diaphragm, not your chest
I’ve had athletes come to me with questions about how to breathe while they run. A common complaint is they just can’t breathe during the metcons with running in them. More likely than not, you’re breathing through your chest and taking short, shallow breaths that are jacking your heart rate up in the middle of the WOD.
This takes practice, but try to push your stomach out as you breathe in. Pushing your abdomen out will open your diaphragm and allow you to breathe easier.
