What is air sustain? #questions

Atıl ULUYÜCE <atiluluyuce@...>

I know it's a silly question but I'm a complete newbie on this. Is there a video or article that explains what should we do in breathing excersizes. I mean, inhale and exhale are ok but what do you mean by sustain?
Thank you very much.

Sorry for confusing you! "Sustain" means holding your breath after exhaling, please find more details here 
Also you can find more tips about the practice here:
