Breath Hold Training for Surfing: Make Hold-Downs Boring

Updated July 10, 2026 · 6 min read · By the Apnea team at SleepyBytes

Here is the hold-down math every surfer should know: a typical wipeout holds you under for 5 to 15 seconds. Even a two wave hold-down in serious surf usually ends within 30 seconds. Almost every surfer's lungs can handle that on paper. What turns a hold-down into a near-drowning experience is not lack of air, it is panic, and panic is trainable.

Why panic, not lungs, is the problem

The urge to breathe is triggered by rising carbon dioxide. During a wipeout, exertion from the paddle and the beating spikes your CO2 fast, the alarm screams early, and an untrained surfer starts fighting: thrashing for the surface, burning oxygen exactly when it matters most. A trained surfer recognises the CO2 alarm as a signal with plenty of margin behind it, goes loose, and lets the wave pass. Same lungs, completely different outcome.

The training: CO2 tables for surfers

CO2 tables are a series of fixed-length breath holds with rests that shrink every round, done sitting at home. The shrinking rests recreate exactly what a hold-down does to your blood chemistry: high CO2, loud alarm, and the choice to stay calm anyway. They are the closest thing to a wipeout simulator that exists on dry land.

A surfer's week: three 10-minute sessions

In the water, the payoff shows up as composure: relax into the hold-down, protect your head, orient, and surface with air to spare. Do not practice breath holds in the ocean or a pool to prepare; the training belongs on land, the composure comes with you.

In the Apnea app

Apnea makes the routine automatic: it builds CO2 and O2 tables from your tested max, times and voices every hold and rest, reminds you on training days, and charts your progress. Surfers use the two-minute test as a benchmark before a trip and watch the number climb between swells. Free to download, works offline, iPhone and Apple Watch.

One honest caveat

Breath hold training raises your ceiling and, more importantly, lowers your panic floor. It does not make you wave-proof: heavy water skills, fitness, and judgement still decide whether you should be out on the biggest days. Train the lungs at home, respect the ocean, and never test breath holds in the water without a trained buddy.

Safety first

Do all table training dry: sitting or lying down on land. Never practice breath holds in water without a trained buddy watching you, never hyperventilate before a hold, and never do breath holds while driving. If you have a heart or lung condition, or you are pregnant, talk to a doctor before training. Blackouts can happen without warning, even to experienced divers.

Ten minutes a day, on dry land

Apnea builds CO2 tables from your max breath hold and coaches you through them with audio. By your next swell, the hold-down math will be on your side.
