ApneaBreath Hold Training for Spearfishing
How long do you need to hold your breath for spearfishing? Less than you think: most productive spearfishing happens on dives of 45 seconds to 1 minute 30, at depths where fish actually are. What separates a good spearo from an exhausted one is not a heroic maximum. It is the ability to repeat calm, relaxed dives for hours, and that is a CO2 tolerance game.
Why CO2 tolerance matters more than a big max
Spearfishing is interval training: dive, hunt, surface, breathe, repeat, thirty or more times in a session. Carbon dioxide accumulates across those repetitions faster than a few surface breaths can clear it, so by mid-session every dive starts with a CO2 debt. A spearo with strong CO2 tolerance stays comfortable and clear-headed on dive twenty; a spearo with a big max but poor tolerance is gasping and cutting dives short. This is exactly the adaptation CO2 tables train, and it is why they are the core of spearfishing breath work.
The stillness dividend: aspetto
Hunting technique compounds the physiology. Aspetto, the ambush technique of lying motionless on the bottom, rewards a relaxed body twice: stillness burns less oxygen, extending the dive, and a calm spearo holds a steadier aim. Breath hold training is aim training in disguise.
Surface intervals: the rule that keeps spearos alive
Rest at the surface for at least twice the length of your dive, three times when diving deeper or later into a long session. A one-minute dive earns a two-minute-plus breathe-up before the next drop. Shortening surface intervals as you get tired is how shallow water blackout happens on a dive that felt routine. And always dive with a buddy on a one-up, one-down system: one hunts, one watches from the surface, every single dive.
A spearo's dry training week
| Day | Session | Why |
|---|---|---|
| Tuesday | CO2 table, 8 rounds | Repeated-dive tolerance, the spearfishing bread and butter |
| Thursday | CO2 table with shorter rests | Simulates late-session CO2 debt |
| Saturday or rest day | O2 table, 8 rounds | Depth reserve and a calmer bottom phase |
| Every 2 weeks | Dry max retest | Rescale your tables as you improve |
Every session is dry, sitting or lying down at home. Ten to twenty minutes. Do not do breath hold tables in the water, and do not train tables the morning before a big diving day; arrive fresh.
In the Apnea app
Apnea turns the plan above into guided sessions: personalised CO2 and O2 tables built from your tested max, audio coaching through every hold so you can stay eyes-closed and relaxed, smart reminders for training days, and a progress chart that shows your tolerance building week over week. Train on iPhone or Apple Watch, fully offline, wherever the week takes you. One note: Apnea is a dry training coach, not an in-water dive computer.
What improves in the water
- Longer comfortable bottom time at hunting depth, without pushing limits.
- Calmer, steadier aspetto and better aim.
- Less gasping at the surface and faster recovery between dives.
- More dives per session at the same effort, which means more chances at fish.
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.
Train on land. Hunt longer in the water.
Apnea builds spearo-friendly CO2 tables from your max and coaches you through them in ten-minute dry sessions, so every surface interval next weekend feels easier.
