I do something in speech therapy called S to Z ratios. I was told it really works the diaphragm. If you know anything about me or have been reading this blog, you’ll know I’m all about the diaphragm! 🙂 This is what I do….I take a big breath from the diaphragm(the chest stays still!) then using the exhale from the diaphragm, make an ‘S’ sound for as long as possible. I then do the same thing with a ‘Z’ sound with the goal being to hold the ‘Z’ sound for as long as the ‘S’ sound. It’s harder to make a ‘Z’ sound.
