Move More, Breathe Less: Rethinking the Breath with Robin Rothenberg

What if much of what we’ve been taught about the breath in yoga is backwards? In this episode, Amy sits down with yoga therapist and author Robin Rothenberg for a frank, eye-opening conversation that challenges one of yoga’s most cherished cues: “take a big breath.”

After a respiratory crisis upended her own health, Robin discovered that the long, dramatic breaths she’d taught for years were making her symptoms worse, not better. The fix ran counter to everything she thought she knew about pranayama: breathe less, build CO2 tolerance, and let the body actually use the oxygen it already has.

Robin opens with a short guided practice, then she and Amy dig into the physiology of carbon dioxide, why “move more, breathe less” became her motto, how nasal breathing transformed her exercise and energy, and why the heart of classical pranayama was never the long exhale but the extension of kumbhaka (breath suspension). It’s a warm, candid, occasionally myth-busting conversation for anyone who teaches, practices, or simply breathes.

Key Takeaways

Bigger isn’t better. Chronic sighing, yawning, mouth breathing, and “taking a big breath” are often signs of over-breathing and distress — not relaxation.CO2 is the catalyst, not the enemy. Carbon dioxide is what releases oxygen from the blood into your tissues. Low CO2 tolerance can drive fatigue, brain fog, achiness, and that “can’t-get-through-the-day” feeling — even when oxygen saturation reads 98–99%.Move more, breathe less. Movement and exercise generate CO2; light, nasal-only breathing keeps it in the system. Together they raise your CO2 tolerance and your real aerobic capacity.Keep your mouth closed. Unless you’re running from a lion or racing to win, there’s no reason to mouth-breathe during exercise. Let nasal breathing set your pace — you’ll get more out of less effort.Pranayama is about kumbhaka. The classical texts emphasize extending the breath suspension after the exhale, practiced several times a day — not the modern habit of simply lengthening the exhale.It’s a transformation, not a quick fix. Dialing the breath down can feel uncomfortable at first because you’re bumping against a subnormal CO2 ceiling. Titrate gradually, raise the ceiling toward normal, and expect it to take months — ideally with skilled support.This is bigger than yoga. Over-breathing is, in Robin’s view, epidemic in our stressed culture and relevant to chronic pain, anxiety, insomnia, and far more — a call for the whole yoga community to
