Building CO2 Tolerance & Training Diaphragm Strength [Resistance Breathing]

Building CO2 (Carbon Dioxide) tolerance is all about being able to manage air hunger. We can do this but reducing both the SPEED of our breathing and the SIZE of the breath. We can monitor the effects using a pulse oximeter as we see SpO2 (blood oxygen saturation) reduce from normal (97-99%) down to hypoxia (92% in this live example).

With this exercise we are adding resistance to our breathing by blocking one nostril which provides additional resistance for the diaphragm to contract against on the inhales, helping to build diaphragm strength and endurance.
