FRC TABLE

Short holds after a passive exhale – on nearly empty lungs.

Your benefit: Simulates the feeling of depth on land while training diaphragm flexibility and CO₂ handling at once.

How the exercise works

1. 1.Exhale normally – don't force – then hold
2. 2.8 short holds at about 25% of your best time, 30 seconds rest
3. 3.Never exhale forcefully, everything stays loose
4. 4.Chest pressure or dizziness: release immediately

Practise breath-hold exercises on dry land only, never alone in the water, no hyperventilation. Stop immediately if you feel unwell.
