Guest Episode: Dr. Garrett Shelby, DC — Dr. G
Topic: Chiropractic, Upper Cervical Care, Functional Neurology, Vestibular Health, and Adapting to Gravity

What if chiropractic is not just about pain relief or “putting bones back in place”?

In this episode of The Functional Code, Dr. Jace and Dr. Addy sit down with Dr. Garrett Shelby, better known as Dr. G, a chiropractor in Cincinnati whose work sits at the intersection of precise adjusting, upper cervical analysis, vestibular function, neurological testing, and helping the body adapt better to gravity.

Dr. G works with patients dealing with migraines, dizziness, POTS-like symptoms, dysautonomia patterns, postural imbalances, athletic performance issues, and complex neurological presentations. He is also the author of The Vital Balance: The Blueprint to Heal From Anything and Living Superhuman.

This conversation explores how chiropractic can evolve beyond the outdated “bone out of place” explanation and into a more accurate model of neuromuscular control, spinal reflexes, vestibular integration, eye movements, muscle tone, and brain-body communication.

In this episode, we cover:

Upper cervical chiropractic
Blair and advanced orthogonal analysis
C1, the occiput, and the upper cervical spine
Functional neurology and brain-body communication
Vestibular function and adapting to gravity
Eye movements and neurological testing
Leg checks, muscle testing, and reflex patterns
Migraines, dizziness, POTS-like symptoms, and dysautonomia
Cranial cervical instability, EDS, and mast cell patterns
Pupil reflex testing and red saturation testing
Saccades, eye tracking, and frontal lobe function
Gait analysis, cerebellum, and coordination
Cervical ocular, vestibulo-ocular, and vestibulospinal reflexes
At-home vestibular exercises and gaze training
Why “out of alignment” may be incomplete
Subluxation as a neuromuscular control problem
Pediatric chiropractic, primitive reflexes, ADHD, and brain development
Vagus nerve stimulation, medulla, and appropriate neurological input
The future of chiropractic

Key takeaway:
Chiropractic is not just about chasing pain. It is about how the brain controls the body, how the body adapts to gravity, and how the spine, eyes, vestibular system, muscles, joints, and nervous system communicate.

Better input can create better output.

Performance Series — Power & Speed
Topic: Force-Velocity Curve, Plyometrics, Sprinting, Elasticity, and Athletic Performance

Power and speed are where the body you built finally has to perform.

In this episode of The Functional Code, Dr. Jace and Dr. Addy continue the Performance Training Series by breaking down power and speed training — how athletes create force fast, why speed is skill-specific, and why the body must build enough tissue capacity to safely express explosive movement.

After covering hypertrophy and strength, this episode moves into the force-velocity curve: how much force you can produce, how quickly you can express it, and how that changes depending on whether you are sprinting, jumping, throwing, skating, swinging, cutting, or changing direction.

Dr. Jace and Dr. Addy explain why power and speed are not just about “trying harder.” They are about biomechanics, nervous system timing, elastic recoil, tendon capacity, tissue absorption, skill acquisition, and full-body force transfer.

In this episode, we cover:

Power vs. speed
The force-velocity curve
Why strength must become speed
MLB pitching velocity and full-body force transfer
Core, legs, torso rotation, and arm whip
Kinetic energy and elastic recoil
The Z-axis and vertical force production
Ground contact, sprinting, and propulsion
Foot, fascia, Achilles, calf, quad, and glute contribution
Bounding, stiffness, jumping, and landing
Change of direction and athletic movement
Why plyometrics should not always come first
Coordination, compensation, and injury risk
Plyometric volume and tendon load
How to train power safely
Lower resistance with higher speed
Explosive reps and longer rest periods
Task-specific power and skill sequencing
Downhill sprinting and assisted speed work
Bands, assisted jumping, and vertical speed
Bryson DeChambeau and golf speed training
Connor McDavid, skating speed, and puck-handling skill
Genetics, body type, and elite athletic development
How to master the human spring

Key takeaway:
Power and speed are trained expressions of tissue capacity, nervous system timing, biomechanics, elasticity, and skill.

The goal is not just to move fast. The goal is to build a body that can absorb force, store energy, recoil efficiently, and express speed without breaking down.

Build the machine.
Connect the nervous system.
Then teach the body to move faster.

Performance Series — Strength Training
Topic: Strength, Motor Units, Nervous System Recruitment, and Injury Prevention

Strength is not just muscle size.

In this episode of The Functional Code Podcast, Dr. Jace and Dr. Addy continue the Performance Training Series with a deep dive into strength training — what strength actually is, why bigger muscles are not always stronger, and how the nervous system learns to recruit the tissue you have already built.

After the hypertrophy episode focused on building the “factory,” this episode explains how strength training fills that factory with workers. Strength depends on motor unit recruitment, neurological drive, coordination, tendon capacity, joint control, and the ability to express force with intent.

Dr. Jace and Dr. Addy break down why strength is task-specific, why isometrics are powerful for rehab and performance, why strength and speed are connected, and why many injuries happen when the muscle can produce more force than the tendon, ligament, or joint can absorb.

In this episode, we cover:

Strength training vs. hypertrophy training
Why size does not always equal strength
Motor units and neural recruitment
Brain-to-muscle communication
Strength as a task-specific skill
Isometrics for strength and rehab
Motor unit recruitment and rate coding
Why strength can improve before muscle size changes
Rep ranges for strength training
Heavy, high-quality reps
Longer rest between working sets
Push-pull supersets
CARs and joint communication between sets
Eccentric loading and tendon preparation
Isometric, eccentric, and concentric sequencing
Diminishing returns and overtraining risk
Detrain, retrain, and stimulate days
Six-to-twelve-week strength blocks
Strength is speed and speed is strength
Adding faster intent into strength work
Medicine ball throws and athletic carryover
Training variability and real-life strength

Key takeaway:
Strength is not just how big the muscle is. Strength is how well your nervous system can recruit muscle, coordinate force, protect joints, and express power in the task you are asking the body to perform.

The goal is not just to lift more weight. The goal is to build force that the body can control, absorb, and eventually express faster.

How does muscle actually grow?

In this episode of The Functional Code, Dr. Jace and Dr. Addy launch a new Performance Series by breaking down hypertrophy — the science of building muscle size, improving tissue capacity, and training smarter for long-term strength, athletic performance, and injury prevention.

This episode goes beyond “lift heavy and get sore.” Muscle growth is not just about damage. It is about remodeling, mechanical tension, protein synthesis, recovery, rep ranges, tendon preparation, nervous system signaling, and how the body adapts to repeated stress over time.

Dr. Jace and Dr. Addy explain why hypertrophy training should not only focus on the muscle belly, but also the tendon, musculotendinous junction, fascia, capillary beds, motor units, and joint capacity. They also discuss why training angles matter, why full range of motion must be earned, why failure training is not always necessary, and why recovery is where growth actually happens.

In this episode, we cover:

Hypertrophy and how muscle actually grows
Muscle belly vs. tendon training
The musculotendinous junction
Mechanical tension and protein synthesis
Muscle remodeling vs. muscle damage
Why “no pain, no gain” is incomplete
Sliding filament theory and movement angles
Sarcomeres, muscle fibers, fascia, and ribosomes
Type 1, Type 2, and Type 2X muscle fibers
Rep ranges for hypertrophy
Why 6–15 reps is a practical starting point
Training close to failure without always going to failure
Weekly volume and sets per muscle
Diminishing returns and overtraining risk
Tendon warm-ups and short-to-long loading
Full range of motion vs. controlled range of motion
Hypertrophy vs. strength, power, and athletic performance
Rate of perceived exertion
Stimulate, retrain, and detrain phases
Recovery, sleep, nutrition, and long-term adaptation

Key takeaway:
Hypertrophy is not just muscle damage. Hypertrophy is remodeling.

The goal is to create enough mechanical tension to signal growth, then give the body enough recovery, nutrition, sleep, and time to adapt.

The muscle belly matters.
The tendon matters.
The nervous system matters.
The joint matters.
And recovery matters more than most people think.

If you want to build muscle that lasts, stop only chasing soreness and start training the entire system.

Guest Episode: Dr. Paul Dickerson
Topic: Chiropractic Neurology, Headaches, Pain, Posture, and Neuroplasticity

What if your headache, neck pain, dizziness, jaw tension, posture issues, or low back pain are all connected through the nervous system?

In this episode of The Functional Code, Dr. Jace and Dr. Addy sit down with Dr. Paul Dickerson, a chiropractic neurologist with more than 40 years of clinical experience and a fifth-generation chiropractic family legacy.

This conversation explores chiropractic neurology, functional neurology, headaches, migraines, cervicogenic headaches, eye tracking, posture, proprioception, jaw function, neck pain, pain pathways, balance, neuroplasticity, and how the brain controls movement, pain, and recovery.

Dr. Paul explains why pain is not always where the problem starts, why the cervical spine can influence headaches, why eye movements and balance matter, and why the chiropractic adjustment may create powerful changes through the nervous system.

This episode also challenges common ideas like “muscle memory” and “pinched nerves,” while explaining how the brain, spinal cord, posture muscles, glutes, shoulder blades, jaw, eyes, and vestibular system all communicate to shape how we move and feel.

In this episode, we cover:

Chiropractic neurology and functional neurology
Headaches, migraines, and cervicogenic pain
The cervical spine and head pain connection
Eye tracking, posture, and balance
The trigeminal nerve and pain pathways
Jaw tension, masseter function, and eye muscles
Pain as a brain-body communication process
Why emotion and stress influence pain
Upper cervical adjusting and neurological input
Motor pool inhibition and the chiropractic adjustment
Proprioception and movement control
Glute medius activation and low back pain
Multifidi, spinal stability, and deconditioning
Shoulder blade mechanics and posture
Breath, vagal tone, and stress regulation
Sound, smell, memory, and brain activation
Why “muscle memory” is a myth
Pinched nerves vs. nerve irritation
Neuroplasticity and lifelong change
Building better athletes through chiropractic care

Key takeaway:
Pain is not just a tissue problem. It is a brain-body communication problem.

Your eyes, jaw, neck, spine, vestibular system, posture muscles, glutes, and core are constantly sending information to the brain. When those signals become altered or poorly coordinated, symptoms can show up as headaches, dizziness, neck pain, back pain, poor posture, or recurring injuries.

The goal is not just to chase pain.
The goal is to understand the neurological patterns behind it.

The brain is always listening.
The body is always signaling.
And better input can create better output.

Episode 133: Organ Series Finale — Thyroid & Adrenals

If you’ve ever felt tired, cold, brain foggy, stressed, wired, gaining weight despite doing the right things, or like your energy system is stuck — this episode is for you.

In the finale of our Organ Series, Dr. Jace and Dr. Addy break down the thyroid, adrenal glands, HPA axis, cortisol rhythm, Hashimoto’s, subclinical thyroid issues, thyroid labs, adrenal fatigue, gut-thyroid connection, stress regulation, sleep, morning sunlight, nutrient support, and how these systems shape energy, weight, hormones, and metabolism.

The thyroid acts like the body’s thermostat, setting the metabolic speed of every cell. The adrenal system acts like the body’s alarm system, helping regulate stress, cortisol, blood pressure, immune function, inflammation, and the daily rhythm that wakes you up in the morning and helps calm you down at night.

About 12% of Americans will develop a thyroid condition at some point, and many people with thyroid disease do not know they have it. This episode also explores why people can have thyroid symptoms even when basic labs still fall inside the standard range.

Dr. Jace and Dr. Addy explain why thyroid and adrenal health cannot be separated from the gut, immune system, liver, sleep, stress, blood sugar, nutrient status, and inflammation.

In this episode, we cover:

The thyroid as the body’s thermostat
The adrenals as the body’s alarm system
The HPA axis and cortisol rhythm
T3, T4, TSH, and thyroid conversion
Hypothyroidism and Hashimoto’s
Subclinical thyroid issues and missed patterns
Why lab trends matter
Why thyroid issues are more common in women
Gut permeability, gluten, and autoimmune thyroid disease
The microbiome and thyroid function
High cortisol and poor T4 to T3 conversion
Sleep consistency and morning sunlight
Stress regulation and recovery tools
Selenium, iodine, zinc, iron, and vitamin D
Ashwagandha, rhodiola, L-theanine, and magnesium
Gluten-free trials for Hashimoto’s
Full thyroid panels and thyroid antibodies
Cortisol rhythm testing
Red flags: fatigue, weight change, cold intolerance, hair loss, palpitations, tremors, heat intolerance, goiter, and menstrual irregularity

Key takeaway:
Your thyroid controls the metabolic thermostat. Your adrenals control the alarm system.

The goal is not just to check one lab marker. The goal is to understand the full pattern: thyroid hormones, antibodies, cortisol rhythm, nutrients, gut health, stress, sleep, and symptoms.

Sometimes “normal” labs do not tell the whole story.

Episode 132: Organ Series — Kidneys

Your kidneys are not just filters.

In episode 11 of our Organ Series, Dr. Jace and Dr. Addy break down the kidneys, hydration quality, electrolytes, blood pressure, blood sugar, NSAIDs, kidney disease, fluid retention, kidney testing, and how to protect kidney function before symptoms show up.

The kidneys filter roughly 50 gallons of blood per day, reabsorbing about 99% of that fluid and excreting only one to two liters as urine. But kidney dysfunction can be silent. Kidney function can decline significantly before standard markers like creatinine clearly rise.

This episode explains the kidneys as the body’s second water treatment plant. They filter waste, reabsorb water and nutrients, regulate sodium and potassium, help manage blood pH, influence blood pressure, support fluid balance, and play a role in blood cell production.

Dr. Jace and Dr. Addy also discuss why hydration is not just about drinking more water. The quality of hydration matters. Water, minerals, sodium, potassium, and magnesium all play a role in how well the body uses fluid.

They also cover why uncontrolled blood pressure and blood sugar are two of the biggest drivers of chronic kidney disease, why chronic NSAID use can stress the kidneys, and why tests like eGFR and urinalysis can help detect early warning signs.

In this episode, we cover:

The kidneys as the second water treatment plant
Why kidney disease can be silent
Kidney filtration and reabsorption
Hydration quality vs. hydration quantity
Electrolytes, sodium, potassium, and magnesium
The kidney-to-heart connection
Fluid retention and blood pressure
Why high blood pressure damages kidney tissue
Why diabetes and blood sugar damage kidney filters
NSAIDs, dehydration, and kidney injury risk
eGFR, creatinine, and urinalysis
Sugar in urine and metabolic warning signs
Potassium-rich foods for kidney and blood pressure support
Himalayan salt, Celtic salt, and mineral hydration
At-home blood pressure tracking
Food order, walking after meals, and strength training
Magnesium and citrate-rich foods for kidney stone support
Red flags: foamy urine, blood in urine, swelling, flank pain, low urine output, fatigue, nausea, and appetite changes

Key takeaway:
Kidney health is metabolic health.

The kidneys depend on healthy blood pressure, healthy blood sugar, intelligent hydration, electrolyte balance, and protection from chronic stressors like dehydration and overuse of NSAIDs.

Your kidneys filter the blood.
They regulate the chemistry.
They manage fluid balance.
And when they struggle, the heart, metabolism, and whole body can feel the effects.

Episode 131: Organ Series — Lungs

You breathe roughly 20,000 times per day.

In episode 10 of our Organ Series, Dr. Jace and Dr. Addy break down the lungs, nasal breathing, mouth breathing, oxygen delivery, CO2 tolerance, nitric oxide, the Bohr effect, diaphragm training, breathwork, humming, HRV, cold exposure, and how breathing can influence stress, sleep, recovery, and performance.

This episode explains the lungs as a delivery truck system. Oxygen is the fuel. Hemoglobin is the truck. But CO2 is the signal that tells the truck when to drop oxygen off at the tissues.

That means CO2 is not just waste. It is a key part of oxygen delivery.

Dr. Jace and Dr. Addy also discuss why nasal breathing matters, how the nose produces nitric oxide, why chronic mouth breathing can affect sleep, dental health, anxiety, oral pH, and facial development, and how training the diaphragm may improve breathing mechanics and athletic performance.

In this episode, we cover:

The lungs as the body’s gas exchange system
Why you breathe around 20,000 times per day
Nasal breathing and nitric oxide production
Mouth breathing and its effects on sleep and oral health
CO2 tolerance and the Bohr effect
Why CO2 helps oxygen release into tissues
Hyperventilation and why it can make you pass out
The diaphragm as the breathing engine
Belly breathing and diaphragmatic control
Resisted diaphragm training
Breathing mechanics for endurance athletes
Nasal strips, mouth tape, and airway support
5.5 breaths per minute for parasympathetic activation
HRV, blood pressure, and slow breathing
CO2 tolerance testing and the BOLT score
Humming and nitric oxide production
Buteyko breathing and box breathing
Rib expansion and intercostal training
Cold exposure as breath-control training
Red flags: shortness of breath, chronic cough, wheezing, sleep apnea, and coughing blood

Key takeaway:
Breathing is not just about getting more oxygen. It is about delivering oxygen efficiently, regulating CO2, supporting nitric oxide, training the diaphragm, improving nervous system control, and helping the body shift between stress and recovery.

Your lungs exchange the gases.
Your diaphragm drives the breath.
Your nose helps filter and optimize the air.
CO2 tells oxygen where to go.

If you can control your breath, you can start to control your physiology.

Episode 130: Organ Series — Brain

Your brain is not fixed.

In episode 9 of our Organ Series, Dr. Jace and Dr. Addy break down the brain, neuroplasticity, the glymphatic system, BDNF, memory, Alzheimer’s risk, gut-brain signaling, sleep, exercise, loneliness, meditation, cold exposure, red light therapy, creatine, lion’s mane, and the habits that support long-term cognitive health.

The brain uses roughly 20% of the body’s energy despite making up only about 2% of body weight. It is constantly processing, rewiring, adapting, filtering, and responding to the inputs you give it every day.

This episode explains the brain as a living computer. Through neuroplasticity, the brain can build and rebuild pathways through repetition, movement, learning, challenge, and experience. Through the glymphatic system, the brain clears metabolic waste during sleep, including waste products associated with Alzheimer’s disease and neurodegeneration.

Dr. Jace and Dr. Addy also discuss why cognitive decline can begin years before symptoms appear, why sleep is one of the most important brain health tools, why loneliness can damage the brain, and why exercise may be the most powerful “brain drug” available.

In this episode, we cover:

The brain as the body’s living computer
Neuroplasticity and brain rewiring
The glymphatic system and brain waste clearance
BDNF and building stronger neural connections
Alzheimer’s disease and early prevention
Sleep quality and cognitive health
Exercise as the best brain drug
Social connection and loneliness
Gut-brain signaling and inflammation
Blood-brain barrier health
Chronic stress, cortisol, and memory
Insulin resistance and Alzheimer’s as type 3 diabetes
Screen time, attention, learning, and child development
Novel experiences, reading, and brain games
Anti-inflammatory nutrition and omega-3s
Creatine and cognitive support
Lion’s mane and nerve growth factor
Cold exposure, norepinephrine, and learning
Meditation and brain structure changes
Red light therapy and photobiomodulation
Red flags: memory changes, mood changes, word-finding issues, getting lost, and wandering

Key takeaway:
Your brain changes based on how you use it.

The goal is to build a brain that can adapt, learn, recover, clear waste, regulate emotion, and maintain strong communication across the body.

Neuroplasticity is the rewiring system.
The glymphatic system is the cleaning system.
BDNF is the growth signal.
And your habits are the inputs.

Episode 129: Organ Series — Heart

Your heart is not just a pump.

In episode 8 of our Organ Series, Dr. Jace and Dr. Addy break down the heart, heart rate variability, VO2 max, cholesterol, ApoB, blood vessels, insulin resistance, zone 2 cardio, strength training, sleep, breathwork, sauna, cold exposure, and the habits that support long-term cardiovascular health.

The heart beats roughly 100,000 times per day and pumps around 2,000 gallons of blood. But heart health is not only about how often it beats. It is about how well it adapts, recovers, pumps, and responds to stress.

This episode explains the heart as the body’s engine. It has a muscle system, an electrical system, a vascular system, and even endocrine functions that help regulate blood pressure, fluid balance, and communication with the kidneys, brain, and blood vessels.

Dr. Jace and Dr. Addy also challenge the basic cholesterol conversation. Around half of heart attacks can happen in people with “normal” cholesterol, which is why deeper markers like ApoB, insulin resistance, inflammation, blood pressure, triglycerides, HDL, LDL particle patterns, and lifestyle factors matter.

In this episode, we cover:

The heart as the body’s engine
Heart rate variability and stress adaptation
VO2 max and all-cause mortality
Why VO2 max is trainable
Zone 2 cardio and cardiovascular baseline
Vigorous exercise and sprint work
Strength training and metabolic health
Muscle as a glucose sink
Sleep and heart recovery
Diaphragmatic breathing and HRV
Nasal breathing and vagus nerve activation
Sauna as passive cardio
Cold exposure and stress resilience
Cholesterol, ApoB, and heart attack risk
Insulin resistance and cardiovascular disease
Smoking and blood vessel damage
Blood pressure, fluid balance, and vascular health
Potassium-rich foods and sodium balance
Red flags: chest pain, shortness of breath, palpitations, fainting, swelling, and unexplained fatigue

Key takeaway:
The heart is an engine that needs training.

The goal is not just to lower cholesterol. The goal is to build a cardiovascular system that can pump efficiently, adapt to stress, recover quickly, maintain healthy vessels, and support long-term performance.

Your VO2 max is a performance metric.
Your HRV is an adaptability score.
Your muscles support your metabolism.
Your daily habits determine how hard the heart has to work.
