You do not need a pool to improve your freediving. A structured dry training routine — breathwork, CO2 tables, and apnea walks — can dramatically increase your performance in the water. Here is how to build one.
The Foundation: Diaphragmatic Breathing
Before every session, spend 5 minutes practising diaphragmatic breathing. Lie flat on your back, inhale slowly for 4 seconds (belly rises, chest stays still), exhale through pursed lips for 6-8 seconds. Repeat 10-15 cycles.
This activates the parasympathetic nervous system, lowers resting heart rate, and prepares the body for a breath-hold attempt.
CO2 Tolerance Tables
CO2 tables build your tolerance to the uncomfortable sensation of breathlessness. The basic structure: fixed recovery period, increasing hold time across sets.
Example: 8 rounds of 2-minute rest / 1:30 hold, building to 2:00 hold across the session. Start conservatively. Never do static apnea training alone, even dry.
Apnea Walks
An apnea walk is a dry breath-hold performed while walking slowly. Take a full breath, walk at a steady pace counting steps, stop before urgent distress. Start with 30-40 steps and build over weeks to 80-100+.
Building a Weekly Routine
- Monday: 10 min diaphragmatic breathing + 15 min CO2 table
- Wednesday: Apnea walk session (4-6 attempts, full recovery between)
- Friday: 10 min pranayama + 15 min CO2 table
- Weekend: Pool or open water session if available
Consistency over 8-12 weeks produces measurable increases in static time and open-water comfort.
