Having done plenty of yoga in my life, I can tell you that breathing exercises are not "bunk."

If someone said "having taken many doses of basically just water in my life, I can tell you that homeopathy is not 'bunk'" would you find that to be a convincing argument?

I think yoga might be a confounding variable in that case.
