CO2 tables train calm recovery under pressure.
A CO2 table usually keeps the breath-hold steady while recovery becomes shorter. Static keeps that structure dry, visible, and conservative.
What changes in a CO2 table
The hold target stays repeatable. The recovery interval gets shorter across rounds. That makes CO2 table training useful for practicing calm discomfort without needing longer and longer breath-holds.
Start manageable
Do not set the hold from an all-out personal best. Use a comfortable dry hold that you can repeat with clean recovery.
Keep breathing normal
Recovery is part of the exercise. Avoid hyperventilation and exaggerated breathing before the next hold.
Save honest effort
A hard or stopped session is still data. Repeating an appropriate table beats forcing a dramatic finish.
Preview first
See the recovery shrink before you start.
Static shows rounds before the timer begins, then guides each Prepare, Hold, and Recover phase.
Apnea table app
CO2 table training in Static
Static gives CO2 sessions the same phase grammar as the rest of the app. You preview the table, start the timer, follow cues, stop if needed, and save the outcome locally. The training remains dry-only and separate from any in-water practice.
If you are deciding between table types, read the CO2 and O2 table guide. If you want a gradually lengthening hold instead, read the O2 table training page.
Example dry CO2 session
A simple beginner CO2 table might use the same dry hold in every round, with recovery decreasing in small steps. For example, a comfortable 1:00 hold could be repeated while recovery moves from 2:00 toward 1:00 across the table. The exact numbers matter less than whether the session stays controlled.
If the early rounds already feel sharp, the table is too hard. If the final rounds require rushed breathing, forced relaxation, or negotiation with yourself, repeat an easier version before reducing recovery again.
When to repeat or progress
Repeat a CO2 table when contractions appear earlier than expected, recovery feels rushed, or the session ends with a high effort rating. Progress only after more than one clean session where the same hold and shorter recovery still feel repeatable.
The CO2 table generator can create a conservative browser table from your current dry static PB. Use the static apnea timer for a simpler dry session, the log template to record difficulty, and the breath-hold progress calculator only for confirmed PB changes.
Common CO2 table mistakes
- Starting from a personal-best hold instead of a comfortable repeatable hold.
- Shortening recovery too quickly because the first rounds feel easy.
- Using hyperventilation to force a table that is already too hard.
- Ignoring the quality of recovery and tracking only completed rounds.
- Training again before the previous session has been properly recovered from.
Safety rule
Do not hyperventilate, do not train in water alone, and do not treat a table as permission to push through dizziness, confusion, numbness, chest discomfort, panic, or anything that feels wrong.
