Burn with Kearns: Functional Fitness Is Your Best Holiday Defense – Kevin Kearns
By Coach Kevin Kearns, contributing writer on fitness and exercise
The holidays are supposed to be joyful — family, celebration, food, connection.
But let’s be honest… for many people, the holidays also bring stress, emotional triggers, travel fatigue, and disrupted routines that derail health, mindset, and momentum.
After 40 years in martial arts and 30+ years training everyone from UFC fighters to CEOs, I’ve learned one truth that never changes:
You cannot control the holidays… but you can control your conditioning.
And in stressful seasons, functional fitness becomes your strongest defense.
Why Functional Fitness Works When Stress Hits
Functional fitness trains you the way your body was designed to move — not in isolated muscle parts, but as a complete human system.
This includes the 8 elements we use at Burn With Kearns:
- Push
- Pull
- Level Change
- Rotation
- Locomotion
- Balance
- Static Strength
- Flexibility
When you train the way real life demands, you build the exact capacities needed to handle holiday chaos:
- Functional fitness slashes stress hormones
Training that uses movement patterns — not just machines — reduces cortisol, stabilizes mood, and improves emotional resilience.
Most people don’t need more motivation…
They need less cortisol.
- It boosts your immunity when everyone else is run-down
Your immune system relies on circulation, breath, lymphatic movement, sleep quality, and recovery.
Functional training improves all of these.
That means fewer colds, fewer setbacks, and more energy when life gets busy.
- It anchors you when life feels unpredictable
A tactical, real-world training approach — like the system I used training 15 UFC fighters — teaches you to stay calm under pressure, breathe through tension, and stay physically ready.
You literally train your nervous system to handle stress.
- It keeps your metabolism firing even when holiday meals hit
Functional training engages multiple muscle groups at once, increasing caloric burn and improving insulin sensitivity — two keys to staying lean through the winter.
- It supports your mental health
After my own battles with depression — the journey that led me to write There’s Light in the Tunnel — I can tell you with full certainty:
Movement is medicine – Functional movement is the prescription.
Your Holiday “Defense Plan” Using Functional Fitness
Here’s exactly how to stay strong through December and hit January with momentum:
- 15 minutes of mobility or band work each morning
This activates your nervous system and keeps joints healthy through cold weather.
- Two 20–30 minute functional workouts a week
Use push, pull, rotation, and level change patterns.
This is how the 45+ busy professionals in our Burn With Kearns programs stay lean.
- Breathwork before stressful events
4–6 deep nasal breaths calm your sympathetic nervous system.
This works whether you’re walking into a holiday party or dealing with emotional family dynamics.
- Stay connected to your community
Fitness is not just physical — it’s support, accountability, and connection.
Our Burn With Kearns community and programs exist for exactly this reason — especially for men 45+, executives, and anyone trying to stay healthy while balancing life’s pressures.
- Remember: Discipline is the ultimate gift to yourself
Not the gym.
Not a diet.
Not a PR.
Discipline.
And discipline is built through functional training — not machines, not shortcuts, not gimmicks.
Why This Matters More After 40
When you hit your 40s and 50s, the body naturally slows:
- Testosterone drops
- Muscle mass declines
- Recovery gets harder
- Sleep quality gets worse
- Metabolism changes
- Stress hits differently
This is why I always say:
Train like a fighter — without taking a hit.
Train functionally.
Train smart.
Train for longevity.
The executives, dads, and weekend warriors I coach aren’t looking for six-pack shortcuts — they want:
- Strength
- Confidence
- Energy
- Longevity
- Protection
- Mobility
- Mental clarity
Functional fitness delivers all of it.
Your Best Holiday Defense? Your Health.
When you stay strong physically, you stay strong mentally — especially during emotionally charged holidays.
Functional fitness isn’t about looking good for pictures.
It’s about feeling powerful in your body.
It’s about protecting your peace.
It’s about being the best version of yourself for the people you love — including yourself.
If you want a plan designed for busy people 40+, check out our programs at BurnWithKearns.com and join a community committed to strength, resilience, and longevity.
This holiday season, defend your health.
Defend your peace.
Defend your purpose.
And as always…
Hustle = Muscle.
