Reuvers™ Breath Training Zones

Stressed Relaxed

Breath training should be strong enough to make it effective, yet calm enough to relax and enjoy the exercise.

Inside the Training

What you do

Five techniques · 15–45 minutes daily

Big Breaths

Full, brisk breaths that engage the lungs completely. Optional, and you choose the intensity.

Breath-holds

Trains your body to deliver more oxygen to your cells.

Slow Breathing

Pacing slowed to a few breaths a minute, which shifts your nervous system toward rest.

Feather Breathing

Gently reduced breathing volume. More oxygen from less air.

Contemplation

Be in the moment. Relaxed focus gives power.

What you train

Five things your body builds

Respiratory strength

The big breaths build respiratory muscle strength.

Oxygen efficiency

Get more oxygen from less air. The core mechanism.

Altered states

Sympathetic-parasympathetic cycling. The autonomic range training.

Nitric oxide levels

Nose breathing supports circulation and oxygen delivery.

Nervous system balance

Deep relaxation every session. The big breaths build flexibility.
