what is "packing"?

[Lil Dragonfly]

One thing I used to do back in my freediving days was take the deepest breath I could, then force more air in by repeatedly filling my cheeks with air and sort of forcing it down. Afterwards I had to swim down immediately; if I stayed at the surface (or on land) it was painful.

Is that what packing is? Or is it something else?

(P.S. I have read tons of webpages explaining what packing is, but they only confused me...)

Yip taking extra gulps of air and forcing it into your lungs is packing.

Just be very careful how you do this, because if you pack too much air into your lungs you'll black out.

Thankfully when this happened to me at the pool my buddy was paying attention.

Thank you

I know what you mean. Whenever I pack my vision goes black for a bit.
