🔄 Execution

The Movement

⬇️ Inhale (Belly Expansion)

What's happening: Diaphragm contracts and descends, creating 360° expansion

1. Breathe in through your nose (or mouth if needed)
2. Let your belly expand FIRST (belly hand rises)
3. Feel expansion into sides and lower back (360° expansion)
4. Chest moves MINIMALLY (chest hand barely rises)
5. Breathing: 4-5 second inhale

Tempo: Slow, controlled, complete

Feel: Belly expanding like a balloon, ribs spreading

Key Concept: "Belly breathing" — diaphragm pushes organs down and forward, expanding abdomen

⏸️ Pause (Post-Inhale)

What's happening: Brief hold at full inhalation

1. Hold breath for 1-2 seconds
2. Maintain 360° expansion
3. Don't force or strain
4. Breathing: 1-2 second hold

Feel: Full, expanded core

⬆️ Exhale (Compression)

What's happening: Diaphragm relaxes, core gently compresses

1. Exhale slowly through mouth or nose
2. Belly gently deflates (belly hand lowers)
3. Feel ribs drawing in slightly
4. Optional: gentle "sssss" sound to control exhale
5. Breathing: 6-8 second exhale

Tempo: Slower than inhale

Feel: Gentle core compression, belly drawing in

Key: Exhale should be LONGER than inhale for relaxation

⏸️ Pause (Post-Exhale)

What's happening: Brief pause before next breath

1. Natural pause at end of exhale
2. 1-2 seconds
3. Don't force it
4. Breathing: 1-2 second pause

Feel: Relaxed, ready for next inhale

💪 Bracing Application

What's happening: Using breath to create intra-abdominal pressure

For lifting/stability:

1. Take 80% full breath (diaphragmatic)
2. Brace your core HARD (like someone will punch your stomach)
3. Hold breath during effort (Valsalva maneuver)
4. Exhale after completing rep/effort
5. Breathing: Breath hold during exertion

Uses: Squats, deadlifts, overhead press, any heavy lifting

Feel: Rock-solid core, intra-abdominal pressure

Key Cues

Primary Cues

• "Breathe into your belly, not your chest" — diaphragmatic focus
• "360° expansion — belly, sides, lower back" — complete breathing
• "Inhale through nose, exhale longer than inhale" — optimal pattern
• "Chest stays relatively still" — not chest breathing
• "For bracing: big breath, brace hard, hold during lift" — performance application

💪 Muscles Worked

Activation Overview

Primary Muscles

Muscle	Action	Activation
Diaphragm	Primary breathing muscle, contracts downward	██████████ 100%
Transverse Abdominis	Deep core stabilizer, activated with proper breathing	████████░░ 80%
Pelvic Floor	Works synergistically with diaphragm	███████░░░ 70%

Secondary Muscles

Muscle	Action	Activation
Multifidus	Deep spinal stabilizer	██████░░░░ 65%
Obliques	Assist in exhalation and bracing	██████░░░░ 60%
Intercostals	Rib cage expansion/compression	██████░░░░ 60%

When Bracing for Lifting

Muscle	Role
Entire core musculature	Creates rigid cylinder of stability
Diaphragm	Maintained in contracted position
Abdominal wall	Pushes out against breath (intra-abdominal pressure)

The Core Canister Concept

Proper diaphragmatic breathing creates the "core canister": Diaphragm (top), pelvic floor (bottom), transverse abdominis (sides), multifidus (back). All work together for optimal core stability.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Chest breathing only	Chest rises, belly stays flat	Shallow breathing, no core activation	Focus on belly rising first
Forcing belly out	Actively pushing belly	Not true diaphragmatic breathing	Let diaphragm naturally push belly out
Shoulders rising	Shrugging with breath	Accessory muscle breathing	Shoulders stay down and relaxed
Holding tension	Rigid, tense breathing	Defeats purpose of relaxation	Stay relaxed, gentle breathing
Hyperventilating	Rapid, shallow breathing	Dizziness, lightheadedness	Slow down, longer exhales

Most Common Error

Chest breathing instead of belly breathing — if your chest rises significantly and your belly stays flat, you're breathing with accessory muscles, not your diaphragm. This is inefficient and doesn't activate your core properly.

Self-Check Checklist

• Belly hand rises MORE than chest hand on inhale
• Feel expansion into sides and lower back (360°)
• Shoulders stay relaxed (not rising)
• Jaw relaxed, no tension
• Exhale is longer than inhale (for relaxation)

Spine	Minimal movement	Neutral	Stability with breath
Ribcage	Expansion/compression	Full	Breathing mechanics
Sternocostal	Rib articulation	Full	Allows rib expansion

The Core Canister

Diaphragmatic breathing creates the "core canister" for stability:

Component	Location	Function
Diaphragm	Top of canister	Descends on inhale, creates downward pressure
Pelvic Floor	Bottom of canister	Responds to diaphragm, maintains upward pressure
Transverse Abdominis	Front/sides of canister	Wraps around, creates circumferential pressure
Multifidus	Back of canister	Spinal stabilization

Benefits for Spine & Core

1. Improved core stability — natural core activation
2. Reduced spine stress — better bracing for lifting
3. Better posture — activates deep stabilizers
4. Injury prevention — proper bracing protects spine

Joint Health Note

Proper breathing is the FOUNDATION of core stability. You can't have a strong, functional core without proper breathing patterns. This is more important than any "core exercise."

❓ Common Questions

Why does my chest still rise when I breathe?

Some chest rise is normal — the goal is that your BELLY rises MORE than your chest. The chest shouldn't stay completely still; it just shouldn't be the primary movement. If your chest rises a lot and belly barely moves, you're still chest breathing.

How long should I practice this daily?

Even 5 minutes daily provides benefits. Ideal: 5-10 minutes in morning, 2-3 minutes before workouts, 10 minutes before bed. But any practice is better than none. Start with 5 minutes once daily.

Should I breathe through my nose or mouth?

Inhale: Nose is ideal (filters, warms, humidifies air). Exhale: Either works. Nose creates slight resistance (good for relaxation); mouth is easier for longer exhales. For lifting/bracing, whatever feels natural.

How does this relate to bracing for squats/deadlifts?

Diaphragmatic breathing creates intra-abdominal pressure (IAP) when you brace. For heavy lifts: (1) Take 80% full diaphragmatic breath, (2) Brace core HARD like someone will punch you, (3) Hold breath during lift, (4) Exhale after rep. This creates maximum spinal stability.

I get dizzy when I practice — what's wrong?

You might be breathing too deeply, too fast, or hyperventilating. Slow down, breathe less deeply, and emphasize LONGER exhales. If dizziness persists, stop and consult a healthcare provider.

Can this really reduce stress?

Yes! Diaphragmatic breathing activates the parasympathetic nervous system ("rest and digest"). Longer exhales than inhales specifically trigger relaxation response. Research-proven for stress/anxiety reduction.

For Mo

When to recommend this exercise:

• User is learning to lift (foundation for bracing)
• User mentions stress, anxiety, or poor sleep
• User has poor core stability or "can't feel core working"
• User is warming up for strength training
• User wants to improve recovery
• EVERYONE should learn this

Who should NOT do this exercise:

• Very few contraindications
• Recent abdominal surgery → Very gentle, get clearance
• Severe respiratory issues → Consult healthcare provider
• Hyperventilation tendency → Extra careful, slow approach

Key coaching cues to emphasize:

1. "Breathe into your belly, not your chest — belly hand rises MORE"
2. "Feel 360° expansion — belly, sides, lower back"
3. "Exhale longer than inhale for relaxation"
4. "For bracing: big breath, brace HARD, hold during lift"

Common issues to watch for in user feedback:

• "My chest rises, not belly" → Still chest breathing, hands-on feedback needed
• "I feel dizzy" → Breathing too fast/deep, slow down, longer exhales
• "I don't feel anything" → May need tactile cueing (hands on belly/ribs)
• "How does this relate to lifting?" → Teach bracing application

Programming guidance:

• Pair with: Everything! This is foundational
• Timing: Morning, pre-workout, post-workout, before bed
• Typical frequency: Daily, multiple times ideal
• Volume: 5-10 minutes per session

Progression signals:

• Ready to progress when: Can belly breathe easily in supine
• Add: Seated, standing, crocodile positions, then dead bug integration
• Regress if: Dizzy, hyperventilating, or having difficulty

Integration with other exercises:

• Essential before: Heavy squats, deadlifts, overhead press
• Pair with: ALL exercises — proper breathing underlies all movement
• Teaches: Bracing for lifting, recovery between sets

Special applications:

For lifters:

• Bracing = big diaphragmatic breath + hold + core brace
• Practice breath-holds with bracing before heavy lifts
• This protects spine under load

For stress/sleep:

• 4:1:8 ratio (4s in, 1s hold, 8s out) is excellent for relaxation
• Practice before bed for better sleep
• Use throughout day for stress management

For athletes:

• Improves oxygen efficiency
• Better recovery between efforts
• Enhances HRV (heart rate variability)

Universal importance:

• This is THE foundation of core stability
• More important than crunches, planks, or any "core exercise"
• Everyone should learn this first
