Freediving Training Toolkit - Apnea Training, Gear & Techniques

📐 Physics Tools

Understand pressure and gas behavior at depth using fundamental physics principles.

Depth → Pressure

Calculate absolute pressure at depth.

Depth (m)

—

Uses approximation: P = depth / 10 + 1 (bar)

Lung Compression

See how lung volume shrinks with depth using Boyle's law.

Surface Lung Volume (L) Depth (m)

—

Boyle's law: PV = constant

Gas Behavior Reference

Quick reminder of how gases compress with increasing pressure.

PV = constant

As depth increases, pressure increases, and volume decreases proportionally.

💪 Training Tools

Build and execute CO₂ and O₂ tables, or track static apnea performance.

CO₂ Table Builder

Generate a CO₂ table: fixed hold time, decreasing rest intervals.

Breath Hold (s) Rest Between (s) Number of Rounds

O₂ Table Builder

Generate an O₂ table: decreasing hold time, fixed rest intervals.

Start Hold (s) Rest Between (s) Number of Rounds

Static Apnea Timer

Time your static apnea attempts with visual progress tracking.

00:00

Target Hold (seconds)

Ready

🎯 Performance Tools

Plan dives, estimate descents/ascents, and prepare breathing routines.

Depth ↔ Time Calculator

Estimate descent or ascent time given depth and speed.

Depth (m) Average Speed (m/s)

—

Time = depth ÷ speed

Breathing Routine

Prepare your pre-dive breathing sequence.

Number of Deep Breaths Breath Interval (seconds)

—

Hyperventilation increases risks. Use controlled breathing.

Recovery Time

Calculate recommended recovery intervals.

Dive Time (seconds)

—

General guideline: Recovery ≥ 2x dive time

📅 Dive Planner

Plan your freediving sessions and structure your training week.

Weekly Training Plan

Structure your week with different training focuses.

Training Focus Sessions per Week

—

Session Duration

Calculate optimal training session duration.

Training Level

—

Rest days are essential for adaptation and safety.

⚠️ Safety Guidelines

Essential safety practices for freediving and apnea training.

🚨 CRITICAL SAFETY REMINDERS

Never freedive alone - Always have a trained buddy present
Train with certified instructors - Professional guidance is essential
Monitor for shallow water blackout - Loss of consciousness can be fatal
Avoid hyperventilation - It reduces CO₂ signals and increases blackout risk
Respect your limits - Progressive training prevents injuries
Know mammalian dive reflex - Understand your body's responses at depth
Maintain fitness - Good cardiovascular health is crucial
Check equipment regularly - Proper gear prevents accidents

Pre-Dive Checklist

Complete before every session.

Buddy present and aware Equipment inspected Safety procedures reviewed Water conditions acceptable Personal feeling good

Emergency Procedures

Know what to do in emergencies.

If buddy loses consciousness:
1. Bring them to surface immediately
2. Clear airway
3. Begin rescue breathing if trained
4. Call emergency services
