Safety Warning
NEVER practice breath holds in water alone. This tool is for dry land training only. Always train in a safe, comfortable position. Stop immediately if you feel dizzy or unwell.
Breath Hold Trainer
Train your apnea with structured O2 and CO2 tables. Set your max breath hold and the tool calculates your training plan.
Slide to set your max. Be honest — this is your comfortable max, not your absolute record.
