Hi Trux, Jome thanks!
i found some interesting links about Uddiyana Bandha, Kudalini and Yoga which seems related:
Some pending questions:
1 - It's curious how yoga exercices are so much times related to advanced freediving, but do you know if there is a method, exercice or technique
"non-yogic" to reduce lung residual volume?
2 - interesting to know like trux said that: "osteopathy may help with skeleton/musculature manipulations to unblock certain limitations and considerably help to increase VC and decrease the RV". Anyone tried that with significant results?
