Think: Longer and stronger with every breath in.
Take as many breaths as you need to engage and elongate your Base-Line.
I found it easiest to work on my breathing whilst standing (in a relaxed manner) or lying on my back. Do whatever feels good for you.
Remember you are healing from your Base-Line out, so that is where your focus should be - it can take a long time to break old habits and many breaths to activate the correct muscles if you are not used to using them.
With every breath in, feel the power of your Base-Line increase.
