Breath Science in Movement: Why Yoga, Pilates, Strength Training, Dance and Sports All Teach It Differently
Understanding the science of breath and how it supports stability, power and nervous system regulation
By Patty Jimenez Hamilton – Mind Body Fusion
After decades of teaching yoga and movement—and earlier experiences as a varsity swimmer in college and a competitive USTA tennis player—I’ve become fascinated by how breathing changes across different forms of movement.
If you study multiple disciplines, you quickly notice something confusing.
Yoga teachers often say:
“Breathe into the belly.”
Pilates instructors cue:
“Pull the abdominals inward and breathe into the ribs.”
Strength coaches tell athletes:
“Expand your abdomen and brace your core.”
Kettlebell systems emphasize pressurizing the torso and even exhaling forcefully during exertion.
At first glance these instructions appear contradictory. In reality, they are all correct depending on the movement being performed.
Breathing is not one-size-fits-all. Different breathing strategies support different physiological and biomechanical goals.
The Physiology of Natural Breathing
The primary muscle responsible for breathing is the diaphragm, a dome-shaped muscle located beneath the lungs.
During a natural inhale:
• the diaphragm descends
• the rib cage expands
• the abdomen gently expands outward
During the exhale:
• the diaphragm relaxes
• the lungs recoil
• the abdomen returns inward
This pattern is known as diaphragmatic breathing and is the default breathing pattern seen in healthy infants and relaxed adults.
Research shows diaphragmatic breathing can:
• improve oxygen efficiency
• reduce stress hormones
• stimulate the parasympathetic nervous system
• improve heart rate variability
Yoga Breathing: Nervous System Regulation
In yoga traditions, breath is closely connected with the nervous system.
Practices such as Ujjayi breathing or Dirga (three-part breath) encourage slow, controlled breathing with expansion through the abdomen and rib cage.
Ujjayi breath is created by slightly narrowing the back of the throat, producing a soft ocean-like sound.
Benefits include:
• calming the nervous system
• improving focus and mindfulness
• synchronizing breath with movement
• enhancing vagal tone
Pilates Breathing: Core Control and Precision
Pilates commonly uses lateral rib cage breathing.
In this method:
• the abdominal wall remains engaged
• the rib cage expands sideways and into the back
• the inhale fills the ribs while the abdomen stays relatively stable
The exhale is slow and controlled, sometimes through pursed lips or a soft “S” sound.
This breathing strategy helps activate the deep stabilizing muscles of the core, particularly the transversus abdominis.
Strength Training Breathing: Creating a Stability Cylinder
In strength training and modern mobility systems, breathing is used to create intra‑abdominal pressure.
The athlete inhales and expands the torso in all directions—front, sides and back—and then braces the core.
This creates a pressurized stability cylinder consisting of:
• the diaphragm (top)
• the pelvic floor (bottom)
• the abdominal wall (sides)
• spinal stabilizers (back)
This technique is often called 360‑degree breathing or “breathing into the belt.”
The Core Pressure Cylinder
When athletes create abdominal pressure, they are engaging what is often described as the core pressure cylinder.
This system includes four key structures that work together to stabilize the torso:
- The diaphragm (top) – the primary muscle of breathing that moves downward during inhalation.
• The pelvic floor (bottom) – muscles that support the base of the core and help regulate internal pressure.
• The abdominal wall (sides) – including the transverse abdominis and oblique muscles that stabilize the torso.
• The spinal stabilizers (back) – muscles such as the multifidus and erector spinae that support the spine.
When these structures coordinate together, they form a pressurized cylinder that supports spinal stability during movement and load-bearing activities.
Understanding the core pressure cylinder helps explain why breath cues differ across yoga, Pilates, strength training, and athletic movement systems.

Kettlebell Power Breathing
Kettlebell systems such as StrongFirst refine this concept further through what is often called power breathing.
Athletes first create abdominal pressure with a deep inhale and brace. During the effort phase of a movement, a short sharp exhale is released while maintaining core tension.
The exhale may sound like:
• “tss”
• “psst”
• “ksh”
This allows athletes to maintain core stability while producing explosive power.
Breath in Swimming
As a former competitive swimmer on my college varsity team, breathing had to become automatic.
In freestyle, my face remained in the water while I gradually released air underwater, then took a quick breath as my head rotated to the side. Similar for butterfly.
In breaststroke, the inhale naturally occurred during the pull phase as the head rose above the water, followed by a slow exhale during the glide.
Backstroke allowed a more natural diaphragmatic breathing pattern since the face remained above water.
Even though coaches rarely analyzed the science behind it, swimmers quickly learn a rhythm that balances oxygen intake, carbon dioxide release, and movement efficiency.
Breath in Tennis
Later, while playing competitive USTA tennis, I noticed another breathing pattern emerge.
Many players naturally release a short, forceful exhale at the moment of impact with the ball. This exhale helps stabilize the core and coordinate the transfer of power from the legs and torso into the racket.
Similar breathing patterns appear in many athletic disciplines including martial arts, boxing, Olympic lifting, and kettlebell training.
Breath in Dance
In partner dancing such as West Coast Swing, breath also plays an important role in movement quality and timing. Many champion dancers teach students to inhale during expanded movements or openings and exhale during contractions or absorption of movement.
Breath can also enhance contrast in dance. An inhale often accompanies movements that expand or rise, while an exhale naturally supports grounding, settling, or softer transitions.
This use of breath helps dancers create musicality and fluidity while coordinating movement with a partner. Like other movement disciplines, dance demonstrates how breath can influence rhythm, control, and expression.
Breath in Animal Flow
Interestingly, systems like Animal Flow do not prescribe a specific breathing technique.
However, during dynamic movements such as kick‑throughs, under switches, and traveling transitions, many practitioners instinctively exhale during the execution phase of the movement.
This pattern mirrors what occurs in strength training, kettlebell work, and sports like tennis.
The body naturally coordinates breath with effort to support stability, rhythm, and force production.
Why These Breathing Systems Seem Different
At first glance these breathing instructions appear contradictory.
But each discipline is solving a different movement problem.
Yoga focuses on calming the nervous system.
Pilates emphasizes control and precision.
Strength training prioritizes spinal stability under load.
Sports often coordinate breath with power production.
Key Takeaways
Breathing is not one‑size‑fits‑all. Different disciplines use breath differently:
• Yoga → calm the nervous system
• Pilates → support movement control
• Strength training → stabilize the spine
• Kettlebell training → produce explosive power
• Swimming → coordinate breath with stroke rhythm
• Tennis → exhale during impact
• Animal Flow → natural exhale during dynamic effort
Understanding these differences allows us to move more intelligently and efficiently across disciplines.
