ABOUT PACKING: Packing is a useful tool in freediving training. Packing must be introduced and used with CAUTION and respect as it carries certain risks and adverse effects for the freediver.
Packing when used in dry stretching routines is very useful for increasing the lung capacity, enabling a freediver to inhale more deeply. It is used widely in pool competitive disciplines and by seriously deep freedivers (70/80m and more).
The risks are important to note; it increases the heart rate, which is counter to what the freediver needs in performance, can cause packing black-outs as it can restrict the flow of oxygen to the brain (if practiced dry this is only dangerous in that you may fall and hurt yourself - practice on a bed!), and there have been a few cases of lung over-expansion and even bubbles entering the bloodstream.
If using packing, start and progress slowly, never going into any kind of discomfort, and keep it appropriate to your level of performance.
DISCLAIMER: Yoga for Freediving courses and videos are not a freediving certification; they do not certify you to freedive in any way. If you are not certified to freedive, you must take basic training with a certified instructor before practicing any freediving exercises in the water.
Neither Sara Campbell nor Discover Your Depths takes responsibility, nor will be held liable for, any accidents or injuries sustained through freediving or any of the exercises taught in these courses.
If in any doubt, please seek medical permission before commencing any yoga or freediving training. And as with all physical exercise, please ensure that at all times you listen to your body, train conservatively and NEVER DIVE ALONE.
Have fun, and keep your training safe, conservative and enjoyable.
