Dr. Belisa Vranich

Dr. Belisa Vranich is a clinical psychologist and the world's leading authority on breathing for combat athletes. Her book Breathing for Warriors is the standard text on the subject, and her methods are used by professional fighters, military units, police departments and elite sports teams across the US.

Here's what she knows that most grapplers don't: you can't out-technique a gassed-out body. The way you breathe under pressure decides whether you stay calm in bad positions or panic and burn out — and almost everyone is doing it wrong. Belisa teaches breathing as a trainable skill, anatomically, from the ground up.

Her work with The BJJ Project brings that system straight to the mats: recover faster between rounds, stay composed under a heavy side control, and unlock the endurance you already have but can't access.
