Rounds9
Rest1 breath
Moderate holds with only a single deep breath in between.
Your benefit: Trains you to stay calm on minimal recovery – like between two dives in the water.
How the exercise works
- 1.Hold about half your best time for 9 rounds
- 2.Between rounds: exactly ONE deep breath
- 3.Deep inhale, long exhale – then straight on
- 4.The trainer cues your inhale and exhale
The one-breath table is modern CO₂ training: because recovery is a single breath, CO₂ rises quickly even though the holds stay short at around 50 percent of your best time. In the pause, focus on one complete calm breath: deep inhale, long exhale – then straight on. This exercise comes closest to the rhythm of real repeated dives and is perfect when you are short on time.
Practise breath-hold exercises on dry land only, never alone in the water, no hyperventilation. Stop immediately if you feel unwell.
