+34.6% diaphragm thickness in 8 weeks. The 2024 science, Tim Emmett's rib injury explained, metaboreflex activation, and 5 field drills — no devices needed.
Will Bosi on Burden of Dreams V17 and Jimmy Webb on Sleepwalker V16 — the neuroscience of timing breath to movement, second by second.
Emotion regulation is not about suppressing fear — it's about meeting intensity skillfully. Tim Emmett's ascent of Era Vella is a masterclass in what happens when the body braces under psychological load.
MBT vs BOLT vs the Huberman CO₂ Protocol — which test is right for climbers? A deep dive into what each measures, how they integrate with Pranaclimb, and when to use each one.
A single breath hold during climbing can physiologically equate to missing 2–3 natural breaths. Understanding why — and when to hold vs. breathe — could transform your performance.
The C:F ratio, ARC training, Zone 2, and how nasal breathing amplifies the capillarization stimulus. The vascular infrastructure of climbing endurance.
The Bellows Breath — sympathetic activation, lung priming, ↑PEFR and pre-climb power. Five research papers and the complete Pranaclimb protocol.
When you hold your breath on a crux, your spleen contracts and releases a surge of oxygen-rich red blood cells. The Pranaclimb cMBT, 3 breath-hold protocols, and 2025 research explained.
Controlled breathing practices can stimulate the growth of new blood vessels through hypoxia-inducible factors. The implications for climbing endurance and recovery are profound.
8 case studies applying the Pranaclimb BR adjustment framework to world-class ascents — from Silence 9c to Sleepwalker V16. W′bal, CP, RCP, and the Scream-Density Override in action.
What is CP? What is W′bal? How does expressive breathing work? 12 deep-dive questions answered from the published research — with tables, thresholds, and the full RPE scale.
