"Alright, boys. Breathing exercises, go."
"Yes, Father."
Cedric watched as his sons sat down in the patch of grass and began breathing rhythmically. Each time they inhaled, a misty arrow seemed to be heading straight to their nostrils, and their exhale was akin to a strong gust of wind.
This was how Cedric trained his sons to be stronger—well, for now at least. They're too young to hold steel, and there's still years away before their awakening ceremony, so his will do for now.
This breathing exercise they're doing isn't really that difficult. In fact, anybody could do it due to how simple it was. It wouldn't require a heaven-defying comprehension to get started with it either. One just needs to follow a steady breathing rhythm and keep at it for as long as they can.
That said, while this might be a simple exercise, it is 'THE' exercise...
