The Breath–Spine–Pelvis Connection
Are You Breathing “ Wrong ”
Breathing seems simple. We do it 20,000 times a day without thinking. But for many performers (and even athletes) breathing habits are holding them back.
From a clinical perspective, the way you breathe directly affects your core function, spinal stability, recovery, and overall performance. If your breath, spine, and pelvis aren’t working in harmony, your body has to “cheat” by overusing other muscles, leading to tension, fatigue, and even injury.
What’s Really Happening When You Breathe
When you take a deep, diaphragmatic breath, your diaphragm lowers and your ribcage expands. At the same time, your pelvic floor and abdominal wall respond by creating intra-abdominal pressure (IAP), the stabilising system that supports your spine like a natural brace.
This is the foundation of true “core strength.” It’s not about six-pack muscles; it’s about deep stability that:
Protects your back from overload
Supports powerful, efficient movement
Improves breath control for singers and actors
Reduces excess tension in shoulders and neck
The Problem: Deep Core Weakness & Stressful Breathing Patterns
Modern life and performance pressures often disrupt this system. Instead of the diaphragm working efficiently with the spine and pelvis, stress drives shallow, upper-chest breathing and jaw tension.
This creates a cascade of issues:
Deep core weakness – the body stops using the diaphragm and the core effectively, leaving the spine under-supported.
Jaw pain & TMJ issues – high-stress performers often clench or overuse jaw muscles when the breath isn’t well-coordinated.
Neck & shoulder strain – secondary muscles kick in to “help” with breathing, causing fatigue and tightness.
Breath inefficiency – reduced control and stamina, especially noticeable for singers, actors, and dancers.
And for performers, this is more than discomfort, it can directly limit projection, vocal quality, and stage presence.
Fight or Flight?
The breath doesn’t just affect muscles and posture, it’s a direct line to your nervous system. Shallow, rapid breathing keeps your body stuck in a stress response, where the shoulders tighten, the jaw clenches, and efficiency drops. By re-engaging the diaphragm and coordinating breath with the spine and pelvis, you stimulate the parasympathetic system, the “rest and recover” mode. This not only calms the mind but also reduces unnecessary muscular tension, allowing performers to access their full range of motion, voice, and presence.
The Drill: Reset Your Breath–Spine–Pelvis Connection
Here’s a simple exercise to reconnect your breathing system:
90/90 Diaphragmatic Breathing
Lie on your back with knees bent, feet on the floor.
Place one hand on your chest and one on your belly.
Inhale through your nose, feeling your lower ribs and belly expand gently into your hand and into the floor/mat.
Exhale slowly through your mouth, allowing your ribs to soften and slide down toward your hips, whilst gently engaging your lower abs.
Repeat for 6–8 breaths, focusing on smooth expansion and relaxation.
Tip: If your chest hand rises more than your belly hand, you’re defaulting to shallow chest breathing. Practice until the belly/ribcage expansion leads the way.
The Breath–Pelvis–Jaw–Voice Connection
What makes breathing truly powerful for performers is how it integrates with the pelvis, jaw, and voice. These systems are interconnected:
The pelvis and diaphragm create the pressure system that stabilises movement.
The jaw directly responds to stress and breathing mechanics, often tightening when the diaphragm underperforms.
The voice relies on efficient airflow and resonance, both compromised when breath is shallow and the jaw is overactive.
That’s why so many high-stress performers experience a mix of breathing dysfunction, deep core weakness, and jaw pain at the same time.

MDH Breathing Coordination Clinic with Darel
At Prehab, we address these issues through our MDH Breathing Coordination Clinic with Darel. This specialised program explores how your breath interacts with your pelvis, jaw, and voice, and uncovering hidden inefficiencies that affect performance and wellbeing.
Performers often describe the experience as “unlocking” their body:
Jaw tension eases.
Breathing becomes fuller and easier.
Movement and voice feel more free, natural, and sustainable.
For singers, dancers, and actors, this integration can be the difference between working against your body and finally letting it support you.
Final Takeaway
The breath–spine–pelvis connection is the foundation of both performance and injury prevention. By training your breath, you train your core — and by training your core, you protect your body while unlocking more efficient movement and voice.
If you’ve been noticing jaw tension, vocal fatigue, or ongoing shoulder/neck tightness, it may not just be stress, it could be your breathing system asking for help.
