Carbon Dioxide is Your Friend

Slow breathing in and out through the nose forces you to breathe correctly and tolerate a more normal balance between oxygen and CO2 in your body.  If you wake up from a night of sleep exhausted with a dry mouth, have been told that you snore, or sleep with your mouth open then you can be confident that this is affecting your ability to utilize oxygen and allow tissues to recover.  

Why you should learn how to squat.

Gradually exposing your tissues to this problem will ensure you get more comfortable with it and your tissues actually get stronger as long as you choose the correct dose of tissue load.
