The Ohm Trifecta
Tools for Breathing, Posture, and Performance

A Systematic Approach to Mobility
Breathing efficiency, posture, and movement are part of an interconnected system. If one area is off, the entire structure compensates.
The Optimal Health Model (OHM) focuses on aligning this system from the ground up with three targeted tools:
- Better Bite: A jaw-strengthening device that supports breathing mechanics by improving jaw stability and airway function.
- Psoas Saddle: A deep-release tool for the hip flexors, easing tension that affects posture, mobility, and even respiratory capacity.
- Sole Spacers: Silicone toe separators that promote foot alignment, enhancing balance and reducing compensatory strain throughout the body.
This blog explores the science behind these tools and how they integrate into a holistic movement and breathwork strategy.
Better Bite: Jaw Position and Airway Function
The Jaw-Breathing Connection
Jaw position plays a subtle yet crucial role in breathing. The alignment of the mandible influences airway openness, and research suggests that jaw-repositioning devices can reduce airway resistance and improve ventilation. Proper jaw positioning encourages nasal breathing, which enhances nitric oxide production, improves oxygen absorption, and reduces unnecessary tension in the neck and shoulders.
However, while some studies show that oral devices may enhance airflow, others suggest no significant effect on overall endurance or performance. The key takeaway? The Better Bite isn’t a magic bullet for athletic performance but serves as a useful tool for jaw stability and airway support, which can aid in breath efficiency.
Progressive Jaw Training for Functional Gains
The Better Bite system includes three resistance levels, allowing for gradual strengthening without excessive strain. Unlike many commercial jaw trainers marketed for aesthetics, the Better Bite prioritises function - helping users train their jaw to maintain optimal positioning during everyday breathing and movement.
- Supports nasal breathing by improving jaw stability
- Encourages balanced tension in facial and neck muscles
- May reduce airway resistance, making breathing feel easier
Considerations for Use
- Overuse can lead to jaw fatigue or TMJ discomfort -> it’s essential to start with low resistance and progress gradually.
- Those with existing TMJ disorders or recent dental work should consult a professional before use.
Psoas Saddle: Hip Flexor Release for Postural Health
Why the Psoas Matters
The psoas muscle connects the spine to the legs, influencing posture, spinal alignment, and even breathing by interacting with the diaphragm. A tight psoas can contribute to excessive lower back arching, limited hip mobility, and restricted diaphragm expansion.
Releasing the psoas has been linked to:
- Reduced lower back pain
- Improved hip mobility and spinal alignment
- Greater breathing capacity due to diaphragm-psoas interaction
Deep Tissue Release for Mobility and Recovery
Think of the Psoas Saddle as your personal deep-tissue therapist - except it never gets tired and doesn’t ask about your weekend while digging into your hip flexors. Just lay down, breathe, and let the tension melt away. Regular use helps:
- Reduce lower back tension by easing excessive lumbar lordosis
- Improve hip flexibility for better movement efficiency
- Enhance breath mechanics by allowing freer diaphragm expansion
Considerations for Use
- Beginners should start with short sessions (1–2 minutes per side) to avoid excessive soreness.
- Individuals with abdominal conditions (hernia, recent surgery, pregnancy) should consult a professional before use.
Sole Spacers: Foot Alignment and Movement Efficiency
The Role of Foot Posture in Whole-Body Alignment
Feet are the foundation of movement. When the toes are cramped due to footwear or structural imbalances, it alters how force is distributed through the ankles, knees, and hips. Toe spacers help restore natural toe splay, reducing strain and improving movement efficiency.
Studies have shown that regular use of toe spacers can slow bunion progression, improve foot mobility, and alleviate pain associated with poor foot mechanics.
How Sole Spacers Support Posture and Performance
Designed to be worn during recovery or activity, Sole Spacers:
- Encourage natural toe alignment for better balance
- Reduce foot pain and improve mobility over time
- May contribute to better ankle, knee, and hip stability
Considerations for Use
- Users with diabetes, neuropathy, or severe foot deformities should consult a professional before use.
- Gradual adaptation is key. Start with short durations (10–15 minutes) and increase as tolerated.
Breath and the Deep Core Connection
Breathing is a full-body movement practice. The way you inhale and exhale creates pressure dynamics that shape your posture, stability, and mobility.
The Ohm’s approach unites key elements of the deep core:
- Feet: The foundation of movement. Proper alignment ensures stability from the ground up.
- Adductors: The inner thigh muscles connect the legs to the pelvis, affecting balance and core stability.
- Psoas: A deep hip flexor that links the spine to the legs, playing a crucial role in posture and breathing efficiency.
- Diaphragm: Your primary breathing muscle, coordinating breath pressure with movement.
- Neck & Tongue Muscles: Often overlooked, these influence airway stability and tension in the upper body.
When these areas work together in sync with breath, movement feels effortless, powerful, and efficient.
💡 How the Ohm’s Tools Optimise This Connection:
- Better Bite supports jaw and airway alignment, reinforcing nasal breathing and reducing upper-body tension.
- Psoas Saddle releases deep core restrictions, allowing for smoother breath-driven spinal movement.
- Sole Spacers restore foot function, preventing compensatory patterns that disrupt balance and posture.
This is not about isolated fixes. It’s about training the whole system to work as one. A strong, adaptive body starts with breath-coordinated movement from head to toe.
Final Thoughts: A Smarter Approach to Mobility and Breath
Improving breathwork and movement is all about understanding how small adjustments in structure and function influence long-term health.
The Ohm’s mobility tools aren’t standalone solutions, but when integrated into a daily practice, they can accelerate progress in alignment, breath efficiency, and overall movement quality.
