I have high blood pressure, should I stay away from RMT?

Respiratory Muscle Training is a safe, highly adherable lifestyle intervention for improving blood pressure and endothelial function in midlife/older adults with above‐normal initial systolic blood pressure.
We completed a study in 2021 that confirmed there had been reduced blood pressure by 2% and improved circulation (artery diameter) but 45% after 6 weeks of regular RMT in post-menopausal women.
