Breathe Light, Slow and Deep: The Breathing Foundation Every Athlete & person Needs

Every athlete trains strength, speed and skill. Far fewer deliberately train the breathing system that supports all three.

Breathe Light, Slow and Deep is one of the foundational breathing practices I use with athletes through the Vincere Protocol™.

It combines three skills: reducing unnecessary breathing volume, slowing breathing rate and improving diaphragmatic breathing mechanics.

I am an Advanced Breathing Coach and certified Oxygen Advantage® instructor, and I use principles from that training alongside the performance framework we have built within Vincere Protocol.

Here’s what each part means, why athletes use it, what the research supports and exactly how to practise it.

The three parts

Light: reduce unnecessary breathing volume

Breathing light means gently reducing the amount of air you breathe until you feel a mild, tolerable desire for a little more air.

The goal is not to hold your breath or fight for air. Your breathing should remain smooth, quiet and controlled.

This light air hunger is used to practise greater comfort with carbon dioxide and reduce unnecessarily high breathing volume.

Slow: reduce the breathing rate

Slow breathing means deliberately reducing the number of breaths you take each minute.

A common starting range is around five to six breaths per minute. One simple pattern is a four-second inhale followed by a six-second exhale.

The exact timing is less important than keeping the breath comfortable, controlled and quiet.

Deep: use the diaphragm

Deep does not mean big.

It means breathing lower through the diaphragm rather than relying excessively on the chest, shoulders and neck.

Place your hands around your lower ribs. As you inhale gently through your nose, feel the ribs expand into your hands. As you exhale, feel them move back inward.

The breath should remain small and controlled.

Why athletes train it

1. Slow breathing can influence autonomic regulation

A 2022 systematic review and meta-analysis published in Neuroscience & Biobehavioral Reviews examined the effects of voluntary slow breathing on heart rate and heart rate variability.

The researchers found increases in vagally mediated heart rate variability during slow breathing, immediately after a session and following repeated practice.

Heart rate variability is widely used as a marker of autonomic regulation. Slow breathing does not guarantee faster recovery, but it gives athletes a practical way to deliberately influence breathing rate and physiological arousal after intense work.

Read the slow-breathing meta-analysis.

2. Structured breathing can help regulate mood and arousal

In a randomised controlled trial published in Cell Reports Medicine, Stanford researchers compared several five-minute daily breathing practices with mindfulness meditation over one month.

All groups improved mood and anxiety. The breathing groups improved mood more than the mindfulness group, and exhale-focused cyclic sighing produced the strongest improvement in mood and reduction in resting breathing rate.

The study was not conducted specifically in elite athletes, so it does not prove that breathing automatically improves sporting performance.

What it does show is that breathing practice can measurably influence mood and physiological arousal — both relevant when athletes need to regain control under pressure.

Read the Stanford breathing study.

3. It develops better breathing mechanics

The Deep component gives athletes time to practise diaphragmatic breathing when the body is not under heavy load.

That matters because changing breathing mechanics during maximal exercise is far harder than learning the pattern at rest first.

At Vincere Protocol, breathing mechanics form part of the Body pillar alongside nasal breathing, diaphragm function, respiratory efficiency and carbon dioxide tolerance.

See how the Vincere Protocol works.

4. It builds tolerance to mild air hunger

The Light component introduces a small, controlled sensation of air hunger.

The aim is not discomfort for its own sake. The aim is to become more comfortable with the respiratory sensations associated with rising carbon dioxide.

This is one of the qualities we track through breathing assessment rather than simply assuming improvement.

5. It gives athletes a practical wind-down tool

Hard training and competition can leave an athlete physically exhausted while still mentally switched on.

Quiet slow breathing can be used after training or before bed as part of a deliberate transition out of high arousal.

It is not a treatment for insomnia. It is a simple skill athletes can use to help settle breathing and reduce stimulation.

How to practise Breathe Light, Slow and Deep

Sit upright in a chair or lie comfortably if you’re practising before bed.

Breathe gently through your nose unless a particular drill specifically requires otherwise.

Allow around 10 to 15 minutes.

Step 1: Deep — 3 to 4 minutes

Place your hands around your lower ribs.

Take a quiet breath in through your nose and feel the lower ribs gently move outward into your hands.

Exhale softly and feel them move inward again.

Keep your shoulders relaxed and avoid deliberately taking large breaths.

Step 2: Slow — 3 to 4 minutes

Keep the breathing quiet and diaphragmatic.

Gradually slow your breathing toward approximately five to six breaths per minute.

One simple rhythm is:

Inhale gently for 4 seconds
Exhale gently for 6 seconds

If that rhythm feels uncomfortable, shorten it. The objective is controlled breathing, not forcing a number.

Step 3: Light — 3 to 4 minutes

Now gently reduce the size of each breath.

Allow slightly less air in than you would normally take while keeping your breathing smooth and relaxed.

You should develop a mild, tolerable desire for more air.

If the air hunger becomes stressful, your breathing becomes irregular or you feel the need to gasp, you have reduced the breath too much.

Return to normal breathing, settle and begin again more gently.

Step 4: Combine all three — around 4 minutes

Now put the three elements together:

Light: slightly reduced breathing volume
Slow: approximately five to six breaths per minute
Deep: quiet diaphragmatic movement through the lower ribs

The finished breath should feel quiet, controlled and relaxed — not forced.

When athletes can use it

After training or competition: 5 to 10 minutes as part of the transition into recovery.
Before sleep: use it as part of a low-stimulation wind-down routine.
Before competition: use a shorter period of comfortable slow breathing when arousal is too high.
Daily practice: regular short sessions give you more opportunity to develop the pattern than occasional long sessions.

Measure your breathing with the BOLT score

The Body Oxygen Level Test, or BOLT®, is a breath-hold measurement used to provide feedback on breathing patterns and tolerance to respiratory stress.

Despite the name, BOLT does not directly measure the oxygen level in your blood.

To perform the test:

Sit quietly and breathe normally through your nose.
Take a normal breath in.
Allow a normal breath out through your nose.
Gently pinch your nose and start timing.
Stop at the first definite desire to breathe — not your maximum breath hold.
Release your nose and resume calm nasal breathing.

Measure under similar conditions each time and track the trend rather than chasing the biggest possible number.

The BOLT assessment is one of the baseline tools used within Vincere Protocol to assess functional breathing, carbon dioxide tolerance and respiratory control.

See the Vincere assessment process.

Where this fits inside the Vincere Protocol

Breathe Light, Slow and Deep is not a complete performance program by itself.

It is a foundation.

The Vincere Protocol™ builds from foundational breathing into three integrated pillars:

Body: breathing mechanics, diaphragm function, nasal breathing, carbon dioxide tolerance and respiratory efficiency.
Mind: breathing for composure, focus and control under pressure.
Performance: transferring those adaptations into training, repeated efforts and competition.

Explore the three-pillar Vincere Protocol system.

Breathing and yoga

Raw Power Yoga also integrates breathwork and meditation into selected yoga classes, particularly slower practices where there is more time to develop awareness and control of the breath.

If your goal is general movement, mobility, yoga and breath awareness rather than athlete-specific performance training, explore the Raw Power Yoga class program.

For athletes, teams and high-performance environments, the performance-specific pathway is Vincere Protocol.

Safety

Breathe Light, Slow and Deep should remain gentle.

Stop if you feel dizzy, faint, distressed or unable to maintain smooth breathing.

If you’re pregnant or have a significant cardiovascular, respiratory or other medical condition, get appropriate medical advice before practising reduced-breathing or breath-hold exercises.

Never practise breath holds in water, while driving or anywhere a loss of consciousness could put you or someone else at risk.

Train it properly

Reading about breathing gives you information. Repeated practice gives you the skill.

The Vincere Protocol™ is built for athletes, professional teams and high-performance environments that want a structured breathing-performance system rather than isolated drills.

BREATHE BETTER. PERFORM BETTER.
