🫁 Frenzel Equalization Frenzel is one of the most important equalization techniques in freediving. Instead of pushing air from the lungs, you use the tongue and throat to compress a small amount of air toward the nose and Eustachian tubes while the glottis stays closed. The key is learning to control the tongue, larynx and epiglottis independently while keeping the throat relaxed. The goal is not to push harder. It is to become more precise, more relaxed and more efficient with the air you already have. 🌊 #freediving #apnea #spearfishing #freediver #diving
